Issues With Nginx Reverse Proxy

[Majoraslayer]

I'm trying to set up Matchering on a reverse proxy because I often work on my audio projects remotely, and would like to use my home server to master tracks. However, I'm having issues figuring out what Matchering needs in an Nginx server block for it to display correctly. Currently I just get an endlessly spinning loading circle. I'm running the Docker container on Ubuntu 23.04.

Below is what my server block currently looks like (with private info changed). I've tried disabling all of the extra proxy settings (I usually use these by default on most things) but the result is always just a constantly spinning circle. Is there a setting inside the container that I need to change to fix the problem, another argument I need to add to my Docker run command, or is something wrong with this Nginx config?

server { listen 443 ssl http2; server_name matchering.example.com; location / { proxy_pass http://127.0.0.1:8360; proxy_set_header Host $host; proxy_http_version 1.1; proxy_buffering off; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; gzip off; }
