SOLVED: Error when playing media

[Duid]

Hi! 
I am using my jellyfin server with a pi-hole on my raspberry pi 4b 8gb. This is proxied by nginx. I seem to get the "Playback failed with error "loading failed". Retry with transcode? (Note this may hang the player.)" error followed by the "This client isn't compatible with the media and the server isn't sending a compatible media format." error when trying to play media via the windows 11 desktop app. On the browser I get the "This client isn't compatible with the media and the server isn't sending a compatible media format." error. On the android app I get the "This client isn't compatible with the media and the server isn't sending a compatible media format." error again. 

This is my nginx config:https://pastebin.com/WvwvhV3N

Looks like it is trying to transcode but isn't able to. What codecs is your media encoded with?

Just for clarification, your Raspberry Pi is running both pi-hole and jellyfin?

Instead of your nginx config, can you post your jellyfin and ffmpeg logs? They are in /var/log/jellyfin/.

It's an mp4 with H264 encoding using avc1.

Yes it is running both pi-hole and jellyfin.

Here is the jellyfin.log: https://pastebin.com/3SvTcNxJ

Here are the ffmpeg logs: https://pastebin.com/vf3tez1H and https://pastebin.com/mbeZZJwz

I found what went wrong. The drive just decided to un-mount. Thank you for the help.
