I can't connect from WebOS Jellyfin

[walmer]

I attempted to connect my self-hosted Jellyfin server on the WebOS client, but after entering my address, I'm stuck on a screen with the Jellyfin background and nothing else(no buttons, text or anything, just the background with the app client colors).

Some informations:

• I'm using DuckDNS as a DNS provider for a local IP.
  
• I'm using Cosmos Server container inside Ubuntu Server, which has Let's Encrypt built-in.
  
• I can connect via browser, Windows client and iOS client.
  
• WebOS version is 1.2.2
  
• jellyfin version is 10.8.13
