VPN connected but no internet: check the failure one layer at a time

The client says connected, but a browser or app still cannot load. That message confirms part of the connection process, not the entire path to every destination. Work through the following layers so that you can identify the cause without changing several unrelated settings at once.

1. Check the network without the VPN

Disconnect the VPN and open a familiar website reachable from your local network. If that also fails, investigate Wi-Fi, mobile data, the router or your ISP first. A hotel or campus network may require a captive-portal sign-in before a VPN can work.

If practical, compare Wi-Fi with mobile data or a personal hotspot. Keep the device and destination the same so that the change is informative.

2. Decide whether all destinations fail

After reconnecting, test one ordinary trusted HTTPS website as well as the affected service. If the ordinary page works, the tunnel may be usable while one platform rejects the exit or has an account-specific problem.

A streaming app, work portal or banking website can apply rules to VPN traffic. Reinstalling the client repeatedly will not necessarily change those rules.

3. Check the account and connection state

Confirm that the right account is signed in, membership is valid and the chosen route is available. Reopen the official app if its displayed state appears stale. Check your device's date and time: a badly incorrect clock can cause certificate and sign-in failures.

Do not keep entering a password into a page with a certificate warning. Verify the domain and resolve the warning first.

4. Review system permission and conflicting tools

Android and Apple systems may request VPN or network-extension permission. Windows or macOS clients may use an official helper. Review the current platform guide to confirm the required component rather than granting unrelated permissions.

Stop other VPN, proxy and traffic-filter tools while testing. Some systems allow only one active VPN connection; browser proxy settings or another network extension can also send traffic to an unavailable service. Note the original setting before making a temporary change.

5. Check routing mode

Smart routing can leave selected local traffic direct, while global mode uses the tunnel more broadly where supported. If one application behaves differently from the browser, its traffic may be taking another path. Choose the supported mode suited to the task, reconnect and repeat the same test.

A direct path in smart routing is outside the VPN tunnel. Global mode can add latency to local services and still cannot guarantee a destination's acceptance.

6. Try one other route

A server or path can be congested, blocked or temporarily unavailable. Select one other listed location, reconnect and test the same site. Record whether the result changes instead of switching through every location without a consistent test.

If another route works, you have useful evidence of a route-specific problem. It does not establish the exact carrier or filtering mechanism without further diagnosis.

7. Consider DNS and device-specific settings

Custom DNS, browser secure DNS and privacy or filtering tools can influence how names resolve. Samsung users should consult the Samsung troubleshooting guide. For other platforms, record custom settings before testing a supported default.

Do not install unknown root certificates or permanently disable security software to make a page load. A warning needs a specific diagnosis.

8. Update through official channels

Use the supported in-app update flow or official download. An old client may be incompatible with current server behaviour, but an update is not a guaranteed cure for every network failure.

What to send support

Provide the device and OS, client version, network type, approximate failure time, visible error and whether another route or network changes the result. Explain whether all websites fail or only one. Hide full account identifiers, payment details, passwords and verification codes.

The connection-failure guide covers a failure to establish the tunnel; slow-speed checks cover a usable but slow connection.
