Getting "HLS Error / otherError / internalException" when playing in web client only

[hheimbuerger]

When starting a specific video in the browser, I get an endless blue loading spinner over the video still image and no buttons, i.e. also no back arrow to return to the Jellyfin selection UI. I cannot find any error messages pointing to a specific root cause.

Latest Jellyfin server (10.10.3), running in a Docker container. Tested with latest Vivaldi and latest Chrome.
The same video loads just fine in other clients (tested with Android client and Android TV client).
Other videos also load in the browser. This one is an old XVID MPEG4 360p

The video opening is not logged on the server, i.e. "X is playing Y on Z" does not appear in the device activity list.
However, transcoding seems to start just fine.

The main log seems to show that it kicked off the transcoding, though:

ffmpeg log has a couple of warnings, but seems to do fine with transcoding:
