How can you tell whether your VPN is working? Don’t rely on the connection icon alone. Compare your public IP before and after connecting, check whether DNS resolution matches expectations, and then test the app you actually need. A web page loading in your browser only confirms that request worked; it does not verify an AI tool, media player, or work app.
What matters: does the target request use the expected route? A changed IP, DNS behavior, and the app’s actual performance should all support the conclusion that the connection is working. In rule-based mode, local sites may keep using your usual route as part of normal split tunneling. Not every request needs to appear to come from the same region.
“Connected” and actually working are different
“Connected” might mean the system tunnel is established, or simply that a local proxy process is running; the exact meaning depends on the client. Proxy clients may also need the system proxy, a virtual network adapter, or in-app proxy settings to route the target traffic. Successfully importing a subscription only means the configuration was read. It does not prove the selected node is available or that an app is using it.
Before testing, note the selected node, operating mode, and the status of the system proxy or virtual network adapter. Rule-based mode chooses direct or proxied connections based on domains, addresses, or apps. Global proxy mode usually sends traffic handled by that client through the selected proxy, but the word “global” alone does not prove every app is covered.
Be clear about what you are testing: a browser connecting to an international site, an AI editor’s chat request, a streaming session, or a remote-work connection. These may use different processes, protocols, and proxy settings. Focus the checks on the target app instead of repeatedly refreshing the same web page.
Check your public IP against routing rules
Your public IP is the address a website sees as the source of a connection. It is not your device’s address on a local network. Choose a lookup page that shows the public address, network, and region. Compare results before and after connecting in the same browser on the same page to avoid differences caused by the test itself.
- Disconnect the proxy, look up and note your public IP as a baseline. There is no need to share the full address publicly.
- Connect to the target node, make sure the client’s required traffic-handling mode is enabled, and refresh the lookup page.
- Check whether the request matched a proxy or direct rule in the client. If the lookup site is set to connect directly, an unchanged IP does not prove the proxy is failing.
- If supported and you understand the effect, temporarily switch to global proxy mode for comparison. Restore the original mode afterward and send the target request again.
A changed IP only proves that the lookup request took a different route. IP databases may take time to update their country and city information, and different lookup sites may report different locations. Do not treat an exact city match as the only measure. Conversely, if the IP stays the same after switching nodes, the nodes may share an exit; check the client’s connection records as well.
Check DNS: resolution location is not the traffic exit
DNS translates domain names into addresses. DNS test pages usually use special test domains to see which recursive resolvers take part in a lookup; they do not show the exit used by ordinary web traffic. A difference between the resolver’s region and the traffic exit may come from proxy settings or from the distributed infrastructure of a public DNS service. A location label alone is not enough to draw a conclusion.
A more useful question is whether domains that should be resolved on the proxy side are still being sent to the local network. If a target domain is configured for remote resolution but continues to use your local provider’s DNS, investigate further. If local domains are meant to resolve locally, that may simply be part of the split-tunneling policy.
Your browser’s secure DNS, system resolver settings, and the client’s DNS module may all be active at once. A browser making encrypted DNS requests does not guarantee those requests use the proxy; their route still matters. Record the original settings first, change one thing at a time, then run the test again and check the client’s records. This makes it easier to identify the cause than changing the resolver, node, and rules all at once.
Domain caching can also affect what you see. If needed, clear the cache using the official instructions for your system or browser, or fully close and reopen the app. The nslookup command can help check responses from a specified resolver, but it may not reproduce the browser’s secure DNS path. It cannot by itself prove that the browser is not resolving domains through another route.
| What you see | Possible explanation | What to check next |
|---|---|---|
| IP lookup still shows the local exit | The lookup domain connects directly, or the browser is not being handled by the client | Check the rule matched for that domain and the actual connection |
| IP changed, but DNS shows the local network | DNS may use a separate local route, or this may be expected split tunneling | Check the test domain, browser secure DNS, and the client’s DNS policy |
| Web pages work, but the target app fails | The app may not use the system proxy, or a background process may use another route | Check the relevant process and domain while using the target feature |
| The target site opens, but its regional content is wrong | Account region, cache, licensing, or exit detection may differ | Check the account and region notices in the target app |
App-by-app testing: check the feature you need
Before testing an app, fully quit and relaunch it to avoid an existing connection continuing to use its previous route. While using the target feature, check the client’s connection panel or logs for the process, destination domain, matched rule, and node. Logs may contain sensitive information; hide subscription links, tokens, and account details before sharing them.
AI tools: test the web app, editor, and command line separately
Working web chat does not prove that editor completions or terminal requests are being handled too. Test the actual chat, completion, or target API request separately, and see whether streaming responses finish. Command-line programs may read proxy environment variables or require their own settings. Do not assume they inherit browser settings; check the tool’s documentation for supported proxy types and options.
Streaming: test playback, not just the home page
Loading the home page, seeing a regional catalog, and successfully playing content are different checkpoints. Check that the content appears in the target app and try to play it, while watching for region or proxy notices. Account region, content licensing, cache, and platform checks can all affect the result. A changed exit IP does not guarantee the catalog will change.
International sites and remote work: check each request separately
International sites may load sign-in, images, and scripts from different domains. If the main page opens but an attachment fails, check the connection for the failed resource. Work apps may handle sign-in, file sync, voice, and screen sharing separately; a successful login does not prove meeting media will work. A corporate VPN may control routing or DNS, so follow your organization’s network policies before making changes.
Common differences in traffic handling across platforms
On Windows and macOS, the system proxy is generally used by apps that support that setting; it should not be treated as a way to force all traffic through the client. A virtual network adapter can cover more cases, but routing, exclusions, and client capabilities still matter. A browser proxy extension may apply only to that browser and cannot configure other apps.
Android clients may let you include or exclude apps, so check whether the target app is in the proxy scope. An iOS VPN status indicates that a related connection exists in the system; it does not prove every target domain follows the same rules. On Linux, desktop proxy settings, terminal environment variables, and system tunnels may also operate independently. This is especially important when testing command-line tools.
If several network-handling tools are running at once, their proxy or routing settings may conflict. Keep one clear test configuration while troubleshooting. On a work device, do not disable security components required by your organization; ask an administrator which tests are allowed.
When it looks connected but traffic is not routed: follow the evidence
- ✅ Check traffic handling first. If a node is selected but the system proxy is off, or virtual network adapter permission has not been granted, the target app may still connect directly.
- ✅ Check the matched rule next. A broad direct rule, an app exclusion, or an outdated rule set may send the target request around the selected node.
- ✅ Check for old connections. Restart the target app after switching nodes and inspect new connections so an existing session is not mistaken for a new route.
- ✅ Check for configuration updates. A subscription link retrieves configuration; it is not a client installer. After updating, confirm the node is still listed and that the selected node has not changed.
- ❌ Do not use a speed test as a substitute. A successful speed test only shows that its test route works. It does not prove the target app uses the same route.
- ❌ Do not keep switching protocols at random. If the app is not using the proxy at all, changing the node protocol will not fix traffic handling.
When testing another route, change one variable at a time and record the result for the target feature. Labels such as direct, relay, or IEPL describe how a route is organized; they cannot replace checks of traffic on your device. Even a working route will not help if local rules send the app the wrong way.
Keep a repeatable test record
Your test record can be simple: note the network environment, client mode, selected node, IP comparison, DNS observations, and what happened in the target app. If a problem occurs, add when it happened and any error message with sensitive details removed. This makes it easier to identify the failing layer than simply saying “it connects but doesn’t work.”
Bottom line: trace the target request from start to finish. Confirm that it enters the client, matches the expected rule, uses the expected exit, and completes the intended action in the app. If the IP and DNS results look right but the app still fails, check account restrictions, platform status, or the app’s own settings rather than assuming the route is not working.
