I found your code via the wizarr discord server. My NGINX server does not run in a docker, but on a different ubuntu server in the same LAN.
When I try to access the wizarr URL via WAN, I get a white screen. All my other *arr apps work as they support URL base configurations.
Looking at my nginx logs, it is looking for files in the "/usr/share/nginx/html" directory of my proxy server instead of the Wizarr server. Not sure how to fix this in the nginx site config (sites-available/default). Any suggestions would be appreciated!!
