If I forward only the ports, which I activated in the NGINX add on, I can not reach my HA instance from the internet. I have to forward all ports to reach my HA instance. I tried it with two different phones via mobile network and a PC via “normal internet” at home (forgot how it is called).
My server is running Home Assistant OS and obviously the NGINX Home Assistant SSL proxy add-on.
I have no idea why this happens. Has anybody an idea? Am I missing something?
