I only saw under Configuration of Nginx the ports 443, 80 and 81.
But I will try your additions. Only in the moment I don’t get Nginx Proxy Manager to start after a reboot of the HA-Pi.
I can find the following in the supervisor log:
20-06-20 21:19:28 ERROR (SyncWorker_1) [supervisor.docker] Can't start addon_a0d7b954_nginxproxymanager: 500 Server Error: Internal Server Error ("driver failed programming external connectivity on endpoint addon_a0d7b954_nginxproxymanager (f7e664fee1382542a4dca8df9ed7f9ee47057b9567ac7c72d2c85800fb228a1a): Error starting userland proxy: listen tcp 0.0.0.0:80: bind: address already in use")
I changed the port 80 for Nginx to 8088, because I have “Emulated Hue” also running on this Pi and that uses port 80.
I added the things you posted to the advanced setting, but nothing changes.
