VPN troubleshooting

VPN Not Working

Fix VPN connection problems by checking network access, app permissions, DNS, WebRTC, split tunneling, system proxy conflicts, and provider server issues.

Run leak checks

Direct Answer

When a VPN is not working, isolate the failure: connection, routing, DNS, browser behavior, app exclusions, or provider server problems. Change one thing at a time.

Separate connection from routing

A connected status does not prove browser or app traffic is using the tunnel.

Check DNS early

Many VPN issues are DNS or split-tunnel problems, not server failures.

Retest with another server

If one server fails, compare another country or protocol before reinstalling everything.

Steps

Reconnect and test another server.
Check IP and DNS after connecting.
Disable split tunneling temporarily.
Test another browser or app.

Checklist

Visible IP changes.
DNS is not the original ISP.
Target apps are not excluded.
Firewall or proxy conflicts are ruled out.

Troubleshooting

Connected but no internet

Switch server, check DNS, and disable split tunneling for diagnosis.

Only one app fails

Review app exclusions, local proxy settings, and firewall rules.

VPN loops with another proxy

Disable other proxy clients before testing the VPN.

FAQ

Why does the VPN say connected but not work?

The tunnel may connect while DNS, app routing, or split tunneling still fails.

Should I reinstall first?

No. First test another server, DNS, and app exclusions.

Can another proxy break a VPN?

Yes. Running multiple routing tools can cause conflicts and proxy loops.
