Playback problem on web client

Hi, I installed Jellyfin on my Tinkerboard with DietPi (Debian). However I’m unable to play my video library in the web client (tested in Firefox and Vivaldi on Win10). When I go to play a movie I just get an infinite loading wheel. Reproducing videos in an external player with stream URL works regularly. Here are the logs when issue occurs:

Any help would be greatly appreciated!

Have you enabled hardware acceleration?
Also could you provide information about the movie?

“ffprobe -i 7 Days in Havana (2012).mkv”,“Type”:“Default”,“Container”:“mkv”,“Name”:“7 Days in Havana (2012)”

I’m using an ASUS Tinkerboard SbC with Mali-T764 GPU witch doesn’t seems to support any of hardware accellerations available in Jellyfin, so I didn’t set one.

Here is the output of ffprobe -i if is what you mean:
