VPN Won’t Connect: A Practical Troubleshooting Order
Isolate internet access, account state, app conflicts, and connection methods before making broad changes to your device.
Start with the smallest check that distinguishes a VPN problem from an internet problem. Keep a note of what you change so you can restore the original setup.
Check the connection underneath it
Confirm that the network itself has internet access. A captive portal, outage, exhausted data allowance, or weak signal can prevent the tunnel from starting. Follow the app’s blocking or portal guidance if it deliberately keeps traffic offline.
Check account and app state
Confirm the subscription or prepaid time is active, the correct account is signed in, and the app is current. Check the provider’s official service-status information if available. A password for manual configuration may differ from the normal website password.
Try one supported alternative
Use another documented server or protocol. Keep the same network while testing so you know which change mattered. A blocked protocol does not establish that the whole service is unavailable.
Look for competing network tools
Another VPN, a browser proxy, work profile, or security product can affect routing and DNS. On a managed device, ask IT before changing those controls. Do not disable the firewall or install an unknown certificate as a generic fix.
Send a useful support report
Include the operating system, app version, protocol, network type, error, and whether normal internet works. Redact credentials, keys, account numbers, and personal network information. If the issue follows a known provider outage, repeated reinstallations may not help.
If you stop testing, restore the desired blocking and connection settings so ordinary use does not continue in an unintended state.
