We have a Home Assistant instance running in the office. I use Pixel 5 on latest Android to access it and it works fine.
However a couple of colleagues use Mi 3 (Android 11, Tailscale 1.16.1) phones and once or twice a week they notice that it is not possible to reach Home Assistant via Tailscale (we use Home Assistant to open gates).
Usually the workaround is to turn off Tailscale and turn it back again. That does not always fix the issue, but after a couple of toggles it starts working.
What information would be useful to report from an Android phone when we notice Tailscale network not reachable next time?
