Nginx Reverse Proxy Set Up Guide – Docker

Its probably just the default NGINX default conf file. A lot in what you posted looks different then mine. You can try mine if it helps. Just replace your “mydomain.duckdns.org” with your actual duckdns domain and the IP address under Home Assistant with your actual machine’s IP address. Leave all the other IP references alone as those are loopbacks within the Swag container itself (for fast CGI and resolver)
