Jellyfin wont load to UI

[kira100000]

Issue:
Jellyfin has been running perfectly on my server until today. I haven't made any changes that I’m aware of, yet now it won’t load past the splash screen.
Symptoms:

• Accessing Jellyfin via
  http://servername:8096
  or
  http://ipaddress:8096
  connects but gets stuck on the splash screen.
  
• Screenshot: https://imgur.com/a/6500dE5
  
• The server is reachable via ping.
  
• The issue persists across multiple attempts:
  • Restarting the Jellyfin container and the entire server.
    
  • Clearing browser and site cache.
    
  • Testing in incognito mode, a different browser, and the desktop client.
    
  • TV apps also fail to connect.
    

Additional Context:

• Tailscale is installed on the server (not sure if relevant).
  
• Installation method: Used the YAMS installer.

Any help would be greatly appreciated! Thanks in advance.
