Jellyfin with traefik no webinterface black screen

[Rifmaster]

Hi,

I am having a strange issue. Jellyfin installed on Truenas via docker. Jellyfin local working fine. But when i try to access jellyfin via my domain using traefik the loading of the page takes long but the screen remains black. This was working before without issues. All other applications using the same traefik settings all work fine. 
Anyone has a idea what might trigger this issue?
