WackyRabbit7 this is most likely a Cookie issue - your browser already had a cookie with an old Token for the previous server, and the UI failed trying to access the server using that Cookie. Clearing the cookies is always a good thing when reinstalling servers.
Then the fix should be out in next version 🙂
The latest, I curl ed the docker-compose like 10 minutes ago
WackyRabbit7 what version of clearml server did you install? Try changing the URL of the browser to <HOST>:8080/login instead of <HOST>:8080/dashboard.
It's an issue that was solved recently, not sure if the fix is out yet 🙂
