Jellyfin / Docker:Playback failed because the media is not supported by this client.

[Darlor]

Thanks for the help.
I deleted the container,

Code:

sudo docker rm 4623b75e6915 -v

 then recreated it again, with modified docker-compose.yml:

Code:

/media/vortex/Zic1:/media

At first start everything works perfectly.
But after restarting the PC, I have the same problem:
access to the Jellyfin interface starts fine, I can browse all the music, but when I start listening I get the following error message:

Code:

"Reading error

Playback failed because the media is not supported by this client."

I tried with Firefox (Linux) , Chrome (Windows 11) and Android Jellyfin application
