Tailscale doesnt work at all

Hey guys,
i am running a Raspberry Pi Node and after the latest big update almost everything is running fine. I am able to connect remotely Via Tor from all my devices, but when I try to open Tailscale, it says “Onionsite not found”. On my Dashboard the Tailscale app is grayed out und “starting” but nothing happens. Of course i tried restarting the node but that doesnt fix it.
Does anyone have the same problem or a solution?
Thanks in advance!
