Before you start

System VPN, Private DNS and battery policies have different effects; background disconnects may be local.

Step by step

  1. Check the official status or announcement page at https://support.google.com/android/. A help page is not necessarily a live status monitor.
  2. Reproduce the Android issue on one exit and record its time, code, stage and duration.
  3. Check whether battery optimization stops the VPN app, then compare Wi-Fi, cellular and background operation.
  4. Compare wired, Wi-Fi or another network while changing only one condition.
  5. If the app is slow but the browser works, compare app and system proxy settings for duplication.
  6. System VPN, Private DNS and battery policies have different effects; background disconnects may be local.

Common questions

Can switching networks fix every Android error?

No. Account privileges, subscriptions, file permissions and service outages require separate checks.

What should I send to support?

Share the time, client version, redacted error code and minimal reproduction. Never share a password, token, cookie or one-time code.
