New media files won't play

[Yurii]

Hi there!
I'm running the jellyfin server in docker container on the fedora 40. The container is run with Portainer. The media folders are located on the cheep external ssd mounted into /mnt/exdisks2 folder.

My trouble is that a first couple of movies and shows i add, are played well. But with next uploads through the server i get the "Playback Error: Playback failed due to a fatal player error." The previous uploads are still loading and are played well.

Here is my docker-compose file:

ervices:
  jellyfin:
    image: lscr.io/linuxserver/jellyfin:latest
    container_name: jellyfin
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Etc/UTC
    network_mode: 'host'
    volumes:
      - /home/{usr_name}/Configs/configconfig
      - /home/{usr_name}/Configs/cachecache
      - type: bind
        source: /mnt/extdisk2/Plex/Movies
        target: /movies
      - type: bind
        source: /mnt/extdisk2/Plex/Series
        target: /series
        read_only: true
    ports:
      - 8096:8096
      - 8920:8920 #optional
      - 7359:7359/udp #optional
      - 1900:1900/udp #optional
     
    restart: 'unless-stopped'

Either jellyfin can't access the files (did you compare permissions to your old files) or the file is damaged.

thanks for help.
Yes, the permissions to all files are the same with all access possible.

So do you think that the problem might be the poor quality of the ssd drive? Though it copies the files, some sectors might be broken?

Can you try playing with a normal media player mpv on linux or vlc on windows?
Does it play?

Hard to tell where it got damaged... usually ssd work or are dead.  I rarely see corrupt data being written.

Try switching the volumes from bind mounts to simple volume mounts.

From

Code:

- type: bind
        source: /mnt/extdisk2/Plex/Movies
        target: /movies

indeed the same files are could not be played in vlc on Linux.
I've tried to delete and upload same files once again. It's interesting that some were playing well, but once I added the other files, the previous stoped working as well.
It's driving me mad...

This doesn't change anything.. the problem stays the same...
