No playback on android tv box

[Starr]

So here is what I did today:
17:40 start jellyfin server
17:42 login to jellyfin on firefox/android smartphone on second attempt (first attempt with incorrect password...) and play series 1 ->plays fine, it creates an ffmpeg log
17:43 play next episode of series 1 on same device ->plays fine, it creates another ffmpeg log
17:43 logoff from jellyfin on firefox/smartphone
17:45 go to chrome/androidtvbox and play Series 2: nothing happens, no new ffmpeg log
17:47 hit next, still nothing
17:50 stop jellyfin server

Here is the file from /var/log/log_20231112.log on the server

Here is the log from journalctl of the server:

Is there any point sharing the ffmpeg logs generated by the play on the smartphone, which works fine?
Edit: here is the first one from 17:42

Is there a log with more verbose of a way to enable it? is there a log on the client side, and where?

thank you
