Hello,
i have tailscale on my home assistant installed Home Assistant Operating System (VM ESXi)
Since a few months I have a problem to reach my instance over browser. The app in android works fine.
The error was: Fehler: Invalid client id / Error: Invalid client id.
Have anyone a idea… i have nothing found on the internet.
PS: THX for all persons who work on or with home assistant 
Very nice Software!
