SOLVED: Error during transcoding

[Kawick]

Hello, I installed jellyfin with Truenas Scale, I have an error when I want to launch an episode, I have the error: "This client is not compatible with the media and the server does not send a compatible format".

Log :
  log.txt (Size: 1.07 KB / Downloads: 29)

I already have an installation of jellyfin on ubuntu (on another server) that works perfectly, which makes me think that the problem isn't with my files.

Os : TrueNAS-SCALE-23.10.2
JellyFin Version : 10.8.13
Client : Web Client (FireFox)
Cpu : AMD Ryzen 9 5900X

Hope you can help me out here,

greetings
