VPN Troubleshooting Guide

01 Establishing a connection

Can't connect at all: first identify the problem layer

“Can't connect” could mean the client won't start, the subscription list is empty, a route connection fails, or simply that the target website won't open. These symptoms occur at different stages and need different fixes. First, note the exact message shown by the client: is it waiting to connect, timing out, showing an authentication error, or already connected? Don't rely on the status icon's color alone. If the app opens but the route list is empty, go to the subscription section. If it shows connected but pages won't load, see Websites & DNS.

First, confirm the basic network works on its own

Temporarily disconnect the client, open a website you normally access directly, and check whether the system asks you to sign in to the current network. Public networks may require you to confirm access in a browser before a connection can be established. If ordinary websites also fail to load, check your Wi-Fi, gateway or network service first; don't keep switching international routes. Reinstalling the client won't fix a basic network problem and could erase the original configuration you need for comparison.

Once the basic network is working, quit any other proxy, acceleration tool or older client that's managing network traffic, then start the VPNLogo client. Multiple programs can change system proxy settings, routes or virtual network interfaces at the same time. Each may look fine while traffic is actually being handled by conflicting rules. On a managed device, security software or network policies may prevent these changes. Check with your device administrator about permissions; don't disable managed security protections or remove unfamiliar system components just to test.

Compare systematically instead of trying things at random

Check your plan status and remaining data in the dashboard, then refresh the existing subscription and test a route that's actually available there. Keep the same target website and client mode, changing only the route. If the original route fails but another works, the issue is more likely with that specific route or its exit path. If all routes behave alike, keep the route unchanged and switch to another available network. If it works immediately on the new network, investigate the original access network first rather than assuming there's an account issue.

If another device is available, test it on the same network with its own client and subscription configuration. If it connects, focus on permissions, time settings, leftover proxy settings or configuration on the affected device. If it fails too but works on another network, the access network is a more likely cause. Don't change several variables at once—for example, switching devices, networks and routes together. Even if that fixes the issue, you won't know which change helped. Record each change to make a support ticket easier to investigate.

Choose the next step based on the error

For authentication messages, first check that your account and subscription are still valid. Don't enter your dashboard password into route settings—subscription configuration and dashboard login are separate. A timeout means the request didn't complete within the client's expected time, but it doesn't by itself prove a server problem. Basic network issues, failed name resolution and local blocking can produce similar results. For certificate or secure-connection warnings, check that your system's date, time and time zone are correct before trying to sign in again.

The goal of this section is to find where the failure occurs, not to test every route. Compare route regions and types on the Nodes page; the dashboard shows what's actually available to you. If network permissions are denied, the client can't create a network interface or the system keeps reporting errors, include the system message in your notes. This is more useful than saying “nothing works” and saves support from asking you to repeat checks you've already completed.

02 Websites & DNS

Connected but can't open websites? Check the web and DNS

When the client shows “Connected,” that only means it considers the connection step complete. It doesn't mean every app's requests are using that connection. If a website won't open, first determine whether the problem affects all sites, international sites or just one domain. Try different types of sites in the same browser, then check with another browser or app. If only one site fails, the cause may be its regional rules, account status or a site-specific issue. Don't immediately change your device's entire network configuration.

Separate DNS lookup from the actual connection

DNS translates a domain name into the address needed to access it. If a domain can't be resolved, the browser hasn't yet reached the stage of connecting to the destination service. And a successful lookup doesn't guarantee the connection will work. You can use your system's built-in query command to check for a response. The commands below query an example domain to demonstrate the process. When troubleshooting, replace it with the domain that's failing; don't include login links, query parameters or account details.

nslookup example.com

Note whether the command returns an address, times out and which DNS server appears in the results. Different networks returning different addresses isn't necessarily a problem: websites may use content delivery networks that assign addresses by region. Look more closely if lookups keep failing, behavior changes significantly when you connect or disconnect, or the client logs also show DNS errors. If the lookup succeeds but the browser still can't open the site, check browser proxy settings, app routing and the site's response instead of repeatedly changing DNS settings.

Browsers, the system and the client may each have DNS settings

Secure DNS in your browser, manual system DNS and the client's DNS policy can all be active at once. A browser that chooses its own lookup path may behave differently from other apps. Note the current setting, temporarily restore the browser's default DNS option and try the failing page again. Don't change DNS addresses in the system and client at the same time. Otherwise, if the page starts working, you won't know which layer made the difference—or why other apps have new problems.

After switching route regions, your browser may still be using an old connection or cached data. Close the site, restart the browser and test again. If needed, compare in a new private browsing window. Private browsing can help rule out browsing data, but it doesn't necessarily disable every extension or system setting. If the site displays a clear regional restriction, account verification request or access-denied message, that's different from a DNS lookup failure. Save the message and follow the site's own rules.

Clear the cache only when there's a reason to

If you're on Windows and suspect the DNS cache is out of date, run the system command below in a terminal, then try the target domain again. It clears your local DNS cache; it doesn't change your route or fix account permissions or restrictions on the destination site. The steps for other platforms vary by system. Don't copy entire scripts requiring elevated privileges from unknown guides. First try reconnecting the client and reopening the app, keeping settings that you can restore.

ipconfig /flushdns

Also check for a manually configured proxy, browser proxy extensions or custom domain mappings. A local proxy address left behind by an old tool may point to a program that's no longer running, blocking the browser while other apps work normally. Before changing anything, take a screenshot and note which settings the current client manages. On managed devices, don't edit the hosts file yourself. If you need help from an administrator, provide the affected domain and what happens during lookup—not just a screenshot of a blank browser page.

If you're still unsure whether traffic is actually going through the client, follow the guide to checking your exit IP, DNS and per-app routing. A change in exit region is a clue, not proof that every app is using the same route. Consider DNS query results, browser access and client connection logs together rather than drawing conclusions from a single check.

03 Speed & routing

Slow speeds and peak-hour slowdowns

Start by defining what “slow” means: a long wait before a page starts loading, video buffering, a stalled file transfer or an AI tool taking a long time to respond. These can involve DNS, network transmission, the destination service or app-specific limits. Note how the same task behaves before and after connecting, then check whether other destinations are also slow. A single speed test can't represent access to every international site and shouldn't be your only measure of route quality.

Set up a repeatable comparison

When comparing routes, keep the device, access network, destination service and app settings the same. Pause other large downloads, cloud syncs and app updates so they don't compete for local bandwidth. Wi-Fi conditions matter too: being far from the access point, nearby wireless congestion or frequent access-point changes can all make speeds fluctuate. If possible, repeat the same task on a more stable local connection to first rule out instability in your home network.

Don't treat downloads from different videos, quality settings or websites as a controlled comparison. Video services may buffer content in advance, file services may limit transfer speeds by account, and changing clients may trigger a different content server. Focus on whether the task completes consistently, whether it keeps interrupting and whether the issue changes when you switch routes. “The page opens, but the video keeps buffering” is more useful for diagnosis than “the speed is bad.”

Understand route types instead of judging by distance alone

IEPL dedicated lines, relayed routes and direct connections describe how traffic is routed; the label alone doesn't mean one will always be faster. The access network to the route entry point, the cross-border segment and the exit path to the destination can all affect performance. A geographically close region isn't necessarily the best path for your current network, and a more distant region won't suit every app. First choose a region allowed by the destination service, then compare available routes in those regions. Don't keep switching to exits that don't meet the service's rules just to chase speed.

For peak-hour issues, record the time and scope

If service is fine during the day but slows down in the evening, record the time window and time zone. Note whether all routes are affected or only certain regions. Keep the original network and task, then try another available route in the dashboard. Next, test the same route on another network. If performance is generally slow on the original network but recovers on another, investigate the access network or related path. If only one route stays slow across different networks, give support its name and the destination service to check.

For long-running tasks, distinguish slow data transfer from waiting on the service. An AI tool's generation time may depend on model processing and account status. If the page loads normally and other network requests complete, don't attribute all generation delays to the route. If a streaming service shows a specific regional message, check the destination site's rules first instead of continually lowering video quality. See the streaming access guide for relevant usage guidelines; confirm actual access on the destination site.

Once you can reproduce the comparison consistently, stop switching routes. Frequent exit changes may cause content servers to choose a new path and prompt some sites to verify your account again. For a support ticket, include the original route, the comparison route, the access network and the specific task that slowed down. There's no need to create an exaggerated speed-test report. VPNLogo covers 110+ countries / 160+ routes, giving you options to find a suitable path—not a promise that every route performs the same for every destination.

04 Connection stability

Frequent disconnects and background drops

When troubleshooting disconnects, first identify when they happen: while the screen is on, only after locking it, when switching networks or after waking from sleep. Then check whether the client actually shows a disconnection, or still says connected while the app has stopped transferring data. A missing background notification doesn't necessarily mean the connection dropped; a persistent notification doesn't guarantee traffic is flowing. Check the system connection state, client status and actual app access together instead of relying on the notification shade alone.

Disconnects in the foreground? Check network changes and conflicts first

When a device switches from Wi-Fi to another type of connection, the existing connection may need to be re-established and ongoing tasks may be interrupted. First test with the access network unchanged to see whether it still disconnects. If it happens only when you move, switch access points or briefly lose the network, focus on local connection stability. Automatic reconnection can help restore the client, but it can't maintain an existing transfer when the device has lost its basic network connection.

Check whether another proxy, security app or network management tool changes the connection at the same time. Some tools replace system proxy settings on startup; others leave behind network interfaces or route settings after they quit. Close any tools you don't need normally, then reconnect the current client. Don't delete drivers. If the logs show a clear network change, interface shutdown or permissions error, save the relevant excerpt. That evidence is usually more useful than repeatedly clicking Connect.

Android: background permissions and battery settings

On Android, check the client's battery use, background activity and data usage in system app settings. Menu names vary by device, so follow what's shown on your system. If the system restricts the client's background activity, allow it to keep running if needed, and make sure power-saving mode or automatic cleanup isn't stopping it. After changing a setting, keep the network unchanged, lock the screen and check again. Compare before and after instead of changing every power-saving option at once.

Some devices also restrict background network access, even if they don't fully close the app. Check background activity and background data permissions separately. Don't install untrusted keep-alive plugins or copy system-modification scripts that require elevated privileges. On a managed device, an administrator may control these policies, and the options you see may not override them. Mention that the device is managed so you don't mistake a system policy for a route issue.

iOS and desktop devices: how to check connection recovery

On iOS, check that the system VPN configuration matches the client you're using and that no leftover configuration is automatically taking over the connection. Network changes, configuration status and background resource management can all affect connectivity; leaving the app open on a transition screen doesn't guarantee the connection will stay active. After unlocking, check the system connection indicator and client status, then reopen the original app to test. If only one app needs to reload, check its background behavior too.

After waking from sleep, Windows, macOS and Linux may rebuild network interfaces and routes. First confirm the basic network is back, then disconnect and reconnect the client. If it fails after every sleep cycle, record what changed in the network and note the client error. Don't repeatedly reset the entire system network. Closing a laptop lid, unplugging a network device and switching networks can happen at the same time. Separate these actions during troubleshooting so each reproduction has a clear trigger.

Keep a record of the original settings before changing background permissions so you can restore them if there's no improvement. Judge connection stability by whether the original task resumes and whether the issue recurs under the same conditions—not by whether the screen stays lit. If different networks and routes all disconnect after the same lock-screen action, focus on the device and background policies. If it only disconnects on a specific route while the app stays in the foreground, compare routes instead of expanding system permissions further.

05 Configuration sources

Subscription update failures and route list issues

A failed subscription update is not the same as a failed route connection. The first means the client couldn't retrieve or parse the configuration; the second means it has a configuration but can't connect. First check whether the client still has the original routes and whether they work. If an old route works but updates fail, the issue may be with the subscription request, login status or configuration parsing. If the list is completely empty, also check that you've selected the right configuration. Don't delete an old configuration that still works; it's useful for comparison.

Check your account status in the dashboard

Use the user dashboard to check your plan, account status and remaining data, and make sure you're signed in to the account you actually use. VPNLogo doesn't require an email address; you can create an account with a username and password. During troubleshooting, verify the username so you don't mix up orders and subscriptions from different accounts. If you just paid and the dashboard hasn't updated as expected, check the order status first. Don't repeat the same payment to fix a client update error.

Monthly subscription data resets each month on the activation date. If you upgrade mid-cycle, the price difference is prorated for the remaining days; don't assume data resets at the start of each calendar month. Data add-ons remain valid until used and never expire, but that doesn't mean the data is unlimited. Check account status and data separately; updating your configuration won't reset data already used. See plan pricing and billing details, and use the account status shown in your dashboard to guide your next steps.

Check the update request and import method

Get the subscription import link for your current client from the dashboard, and confirm you've selected the right client type. Different configuration formats can't be made interchangeable by just changing a file name. If copying manually, check for missing characters, extra spaces or line breaks. Don't copy the page title or instructions along with the link. If the dashboard offers a direct import, use the matching option and then check that the client added the configuration. Clicking import repeatedly may create several similarly named configurations, making it easy to update the wrong one later.

If the import link doesn't open the client, first confirm the right app is installed and opens normally, then check whether your system allows it to handle import requests. A request the system doesn't pass to the client is a different problem from a subscription server rejecting it. You can add the subscription in the client using the method shown in the dashboard, but don't paste your actual subscription URL into online converters, public forums or shared documents. Treat it as private access information, not an ordinary webpage link.

Find out whether the error occurs during download or parsing

For a network timeout, first check whether the dashboard opens normally, whether you've completed any network access confirmation and whether existing proxy rules are blocking the client's subscription update. For a parsing error, check the subscription format, client compatibility and configuration completeness. If the error text looks like a webpage, login prompt or service error page, the client may not have received the expected configuration. Record the error type and a short summary; don't upload the full response, which may contain private parameters.

Whether an update needs to go through the existing connection depends on the client settings and request route. Don't insist that the proxy must always be on or always be off. Note its current state, then test an update both with the connection active and with it disconnected, and compare the results. If the old configuration still connects, keep it as a working route while you troubleshoot the update. If both states fail but the dashboard opens normally, include that difference in your ticket to help distinguish a configuration request issue from dashboard access.

After recovery, confirm that the correct configuration is enabled and check that the routes have updated. You can disable duplicate configurations first, then clean them up after confirming everything works. Don't risk deleting your only working source. For a support ticket, provide your platform, the client display name, the update error, dashboard status and whether the old routes still work. Support needs to know which step failed—not your account password, full subscription details or private payment information.

06 App routing

Proxy not working in just one app?

If your browser works but one app doesn't, first check whether that app uses the same network route. System proxy settings, in-app proxy settings and client routing rules can all work independently; not every app follows the system proxy. Some apps read network settings only at startup and won't respond to changes right away. Quit the affected app, connect the client, then reopen the app and test the same destination. This avoids mistaking a stale connection for a new route problem.

Compare routing modes and app coverage first

Check the client's current mode and which rule matches, then confirm whether the affected domain is assigned to the intended route. If the client offers a temporary global proxy mode, note the original setting, use global mode briefly for comparison, then restore the original mode. If it works globally but fails in rule mode, check the routing rules or domains used by the app. If both modes fail, look at the app's own proxy settings, account status and exit region rather than assuming the rules are wrong.

Apps often connect to more than one domain. Login, static assets, content generation, file uploads and real-time connections may all use different addresses. So “the homepage loads” doesn't mean every feature is working. Look for failed requests in the log during the same action, but don't add every domain you see to the rules indiscriminately. First identify the failing action and whether its related requests are consistent, then ask support to help assess them. Overly broad rules can change routes for other apps and introduce new issues.

Different platforms, different places to check

Desktop command-line tools can behave very differently from browsers. A terminal process may read its own proxy environment variables while the browser uses system settings; background services may run in yet another environment. First check how the tool you're using handles proxy settings, and look for settings that point to an old program. Don't copy commands with a hard-coded local port; use the address and port the current client actually listens on. Never put account passwords in terminal history or public configuration examples.

Separate connection issues from service rules

AI tools and streaming services may check your exit region, account eligibility, payment region and session status. A website loading but asking you to verify your account doesn't mean the route isn't working. An app saying your current region isn't available won't be fixed by refreshing repeatedly. First check which regions and account conditions the service allows, then select a matching route and keep the session stable. Frequently changing exits adds variables to troubleshooting and isn't a reliable fix for every access problem.

For Claude, read the guide to region detection and route selection to understand the difference between your network exit and account environment. For iOS app access and store region issues, see the iOS client and configuration guide. These guides explain where restrictions may come from; they don't promise that a particular route can override a platform's account requirements. Support can't change account decisions made by third-party sites.

Real-time communication and image-generation apps may also rely on persistent connections. If text pages work but a generation task stops, check whether it fails only when the app goes into the background, the network changes or you upload something. For Midjourney and Discord issues, see troubleshooting image generation and persistent connections. Support can better distinguish a routing issue from an app-side problem if you provide the app name, the action that failed, the error text and a browser comparison instead of just saying “this app doesn't work.”

After comparing, restore any temporary modes you changed and keep only adjustments you've confirmed work. If you need to change routing rules long-term, save the original configuration and note why. App updates, changes to destination domains or system settings can all affect existing rules. If the issue returns, check which rules are actually matching instead of assuming a previously working rule is a permanent fix.

VII Device environment

Device limit alerts and configuration conflicts

VPNLogo allows unlimited simultaneous devices. If the client shows “device limit exceeded,” “connection limit” or a similar message, don't assume it means this service limits the number of devices. The message might come from an old configuration, another service, the client's own interface or a third-party app's account rules. First check where it appears: in the user dashboard, during the client connection process or on a third-party website. Each source needs different troubleshooting. Don't keep changing your VPN subscription because a third-party app has a restriction.

Check the active account and configuration source

A client may contain several subscriptions or manually added nodes. Similar names make it easy to choose the wrong one. Check your account in the dashboard, then verify which configuration and route list are active in the client. Don't rely on a custom display name alone. If you've just moved from another service, disable its old configuration and confirm what's selected now. You don't need to sign out of every device that works or delete all your old configurations. Keeping the source information helps identify where the message comes from.

Unlimited simultaneous devices doesn't mean settings sync automatically across them. Each device still needs the right client for its platform, its own configuration and a verified connection. Sharing a network also doesn't mean every device uses a computer's proxy. If the client is running only on a computer and other devices aren't configured, they usually won't automatically get the same route. Verify each device separately to avoid mistaking local network setup for an account capacity issue.

Check old proxy settings and permissions instead of resetting everything

If access still fails after you quit the client, the system may have kept a manual proxy setting even though the local program has stopped. Open your system's network settings, note the current proxy configuration and check whether it still points to a disabled tool. Normally, the client you're using should manage its own settings. If they're set by an organization or you don't know where they came from, ask an administrator before changing anything. Restore the basic network connection, then reconnect the client and see if the issue remains.

Problems with network extensions, virtual interfaces or security software permissions can also prevent connections. Check for system authorization prompts and follow the client's normal authorization steps. Don't troubleshoot by turning off all protections, deleting system drivers or running unknown repair scripts. If the system explicitly refuses to create an interface, save the error message and note whether the device is managed. These issues require checking the device environment; adding more devices or changing plans won't fix them.

Use the correct download source for your platform

Download the client from the user dashboard. Supported platforms: Windows / macOS / iOS / Android / Linux. Sign in to get the client and subscription; an active plan is required for the iOS download. Don't download lookalike apps from search results just to test, or use configuration files forwarded by someone else. A mismatch between the installer source, client type and subscription format can turn a simple configuration issue into several problems that are difficult to compare.

If you need to reinstall, first save a note of your settings without any private access details, and make sure you can still sign in to the dashboard and retrieve your subscription. Consider reinstalling only after quitting normally, checking the configuration and restoring permissions haven't helped. Find out whether uninstalling will also remove configuration files, and don't erase your only working configuration or all error logs. After reinstalling, first verify the connection with default settings, then restore custom rules one at a time to avoid bringing the faulty configuration back.

If the message still appears to involve a device limit, send support the exact text, where it appears, your platform and the configuration source. Confirm that you've checked the current VPNLogo account. In screenshots, hide private information that isn't needed to troubleshoot; cover subscription links and QR codes. If a third-party app alone reports too many connections, its account rules are responsible. Adding more clients or switching routes won't usually explain the cause—contact that app's account support instead.

The key is to keep configuration sources identifiable and each device in a state you can verify. If a new issue occurs, return to the last working configuration instead of trying the same changes on every device. Keep devices that work as a comparison; don't break a working setup just to make every device's settings identical.

08 Resolution & support

Verify recovery and prepare your support ticket

Don't judge recovery just by whether the connection button shows success. Retry the task that originally failed and confirm it completes, then check that other apps that worked before still work. If the issue involved background activity, a network switch or waking from sleep, repeat the same action to verify. Review temporary global modes, DNS changes and system permissions one at a time, deciding whether to keep or revert each. The setup is ready for ongoing use only when the original issue is resolved without introducing new ones.

When to stop troubleshooting on your own

Contact support if the basic network and account are working but the same error occurs across different networks and other routes; subscription updates keep failing while the dashboard works; a route repeatedly fails under comparable conditions; or the client shows an unfamiliar permissions or configuration error. You don't need to prove the problem is on the service's side or test every device and route. Share the comparisons you've already completed so support can start with a clearer picture.

If your basic network itself is unavailable, resolve the access network issue first. If a third-party site is enforcing account or regional rules, support can help distinguish a network-layer issue but can't replace an appeal to that platform. If your device is managed by an organization or an administrator has restricted network permissions, mention that too. Clarifying these limits doesn't mean your issue is being ignored; it helps support understand which settings you can't change and avoid asking you to repeat steps you can't perform.

Describe what happened in order, not just your conclusion

Submit feedback through the support ticket form in the user dashboard. Start with the time and time zone, device platform, client display name and exact error. Then list the network type, route name and action that failed. Finally, summarize what you compared and the results. You don't need to write down every click, but support should be able to reconstruct what worked before, what you changed and what happened afterward. “It doesn't work” or “it's really slow” alone is too vague to reproduce.

In screenshots, include the error and only the context needed to understand it. Hide full subscription URLs, QR codes, account passwords and private payment information. Check logs before sharing them and provide only a summary from the relevant time period—not your entire browsing history. If you're unsure whether a log contains access details, describe the error type first and ask support which excerpt they need. Never post private information on a public forum and then link to it in your ticket.

Keep follow-up messages on the same thread

If anything changes after you submit your ticket, add the new results to the original ticket and say what you did before the change. Don't combine a resolved issue with a new one as if they had the same cause. Follow support's instructions one change at a time, and report what you actually observe instead of just saying “I tried it.” If you can't complete a step because you lack system permissions or the menu isn't available, say so. Don't try to force it with an untrusted replacement script.

You can troubleshoot the network while checking an order, data balance or refund. VPNLogo offers a 7-day no-questions-asked refund; see the Terms of Service for details. Payment methods: Alipay / WeChat Pay / USDT. Don't overlook the account status shown in the dashboard while troubleshooting, and don't select the same plan again to fix a client error. To check an order, share only the necessary details through your signed-in dashboard—not your payment account credentials.

For everyday use, keep configuration sources clear, update subscriptions from the dashboard and note the original state before making changes. For first-time installation and import, follow the Quick Start Guide. For common account questions, see the FAQ; for contact details, visit Contact Us. This guide helps narrow down the cause step by step. It doesn't override the destination service's rules, and you don't need to be a network expert to use it. Accurately describing what happened is already an important part of effective troubleshooting.
