SOLVED: Playback fail the first time

[Squid]

Hi.

I have this tv show:

Code:

Video
1080p HEVC SDR
Audio
English - Dolby Digital+ - 5.1 - Default

"Playback filaed due to fatal player error" in browser.

in jelly fin client (linux) i get: 

Code:

"Playback failed with error "loading failed". Retry with transcode? (note thjis may hang the player)."

Cancel retry

If i press retry, it starts, and checking playback info it states:

Code:

The other few days ago i reinstalled my proxmox server and got gpu passghrough back up, and nvidia-smi in the jellyfin container works:

I have enabled transcode in jellyfin and restarted it.

Before i reinstalled my host, it worked flawlessly, and the container is/was only backupped and restored between reinstalls, so the jellyfin container is exactly the same as before.
