Jellyfin Random Log out on Playback

[TheDreadPirate]

Remove the /web location in your nginx config. That was deprecated in 10.9 and needs to be removed. Not sure if that is the root or the problem, but we should eliminate it as a factor. Also, buffering should not be enabled. It really doesn't benefit Jellyfin.

Can you replicate the problem then share your Jellyfin log via pastebin?

Here is my nginx config for reference.

Code:

server {
    listen 50443 ssl;
    listen [::]:50443 ssl;
    http2 on;
    server_name jellyfin.domain.tld;

    ## The default `client_max_body_size` is 1M, this might not be enough for some posters, etc.
    client_max_body_size 20M;

    # use a variable to store the upstream proxy
    # in this example we are using a hostname which is resolved via DNS
    # (if you aren't using DNS remove the resolver line and change the variable to point to an IP address e.g `set $jellyfin 127.0.0.1`)
    set $jellyfin 172.16.100.10;
