LG WebOS Error Code 27

[dnightbane]

Hello! I'm having trouble accessing my server from my LG c2 using the LG Store client, specifically, when I enter the URL for the server and hit continue it fails with error code 27.

Playback works fine in the browser and on my pixel 8 pro.

I am hosting jellyfin inside docker (latest tag) with nginx as a reverse proxy using the following nginx configuration:

Code:

server {
    listen 443 ssl;
    http2 on;
    server_name jellyfin.domain.com;

    ssl_certificate    /etc/nginx/ssl/domain.com/domain.com.crt;
    ssl_certificate_key /etc/nginx/ssl/domain.com/domain.com.key;

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