After enabling a VPN, open a DNS leak test and compare the detected DNS provider and region with your expected VPN location.

If DNS requests bypass the tunnel, try another protocol, update the app, change browser settings, or use a different VPN client.

Repeat the test after reconnecting and after switching from Wi-Fi to mobile internet.
