SOLVED: Some Movies Won't Play on Android TV but works on other devices (web browser, phone)

[DrZ]

Hi everyone,

I'm running Jellyfin in a Docker container, and everything works fine on my phone and web browser. However, on Android TV devices (Firestick & Google TV), some movies refuse to play. When I click on the movie in the catalog, nothing happens—no loading, no error message, just nothing. No error messages appear, and the server logs show nothing when trying to play these files.

Jellyfin versions:

• Server version: 10.11.0
  
• Web version: 10.11.0
  
• Build number: 2025021314
  

I've already tried:

• Clearing cache & data on the Jellyfin app
  
• Restarting the server & devices
  
• Checking different playback settings
  

Still no luck. Has anyone encountered this before or have any ideas on what to check next?
Thanks!
