Jellyfin stops playing with WebOS client

[StarZ3r0]

Hello!

I'm new the forum, I read the forum before, but I registered because I had a problem.
The client is a Jellyfin application running on LG C3.
The played 4k movie stops at various times, but usually within 0-5 minutes after startup.
The ones I tried:
- update the server application (under Debian 12)
- reinstall the application on the TV
- checked the "prefer fMP4" setting, but it was turned off by default for me

I have attached the two logs that the server creates.

Thank you very much if you can help.
