Movies not loading

[Cryotan]

I've been enjoying Jellyfin for a long time, however I just can't seem to be able to play movies on my mobile devices. The loading icon stays forever when trying to play.
It only happens with movies and not with episodes. The same file can be played on my desktop using the webversion of Jellyfin but not my phone, iPad and modded Nintendo Switch. I'm not able to play any movies aside from episodes.

Here is what I tried doing:
- Reinstalling Jellyfin on my Pi 4B 8GB
- Deleting all of my browsers cookies/settings
- Using a different file
- Using a different movie

I will provide two logs, one of which is the log of my desktop where the movie plays and the other one being my phone where the loading takes forever.

Why not use our actual app instead of Safari on your phone?

I tried the app before but it has the same issue as on the webversion.

Try installing Swiftfin. It is much newer and should better than Jellyfin Mobile or your browser.

I'm not sure what can be done for the Switch. I don't see anything in your logs that points to a reason why only movies are problematic on some devices.

Swiftfin gives me the same result unfortunately. However I’ve installed the app Infuse and added my Jellyfin server from there and now movies play just fine. It does take a short minute to load but i’m satisfied.

Thank you for your help.
