Jellyfin WebUI randomly died

[pinta]

Hi! 
I have jellyfin 10.10.6 installed on my Ubuntu-server based pc. It was great untill one day it decided to die on me. I cant open the webui anymore while yesterday night it was fine. I didnt updated anything or else, the pc was in idle. I tried to remove and reinstall but it doesnt fixed it. Any recommendation how to fix it up? 
Thanks!

Try clearing the browser cache and cookies? I've found after performing an update the web UI will stop working after a random period of time and is only fixed by clearing the browser data.
