Hey thanks for the quick reply. So first, I am sure my port forwardings and Nginx is working correctly on 10 other containers I have on proxy. Now, I haven't used custom configs much unless I am laying Authelia SSO on top of something so I am a bit wet behind the hears in this area.
So in this case I have not input anything into the custom config area. Maybe this is my problem. I only have basic stuff like caching assets & block common exploits on. My SSL cert is a letsencrypt that blankets my domain (*.mydomain.com).
I have remapped the OP container port to 3021 but I can try it with 8080.
