Hello everybody,
I found a strange behavior with my setup. Hassio is running in a docker on my server, the Duckdns and Ningx add-ons are running and the http section in hassios config is empty, as required by Nginx. My IPS only grants me an ipv6 address, I have a AAAA DNS entry pointing to my ipv6 adress.
The funny thing is, that I have to open all incoming ports in my router and point them to port 443 to get access to hassio from outside my network, connections via IP:8123 are still working. If I open only 80 -> 80 and 443 -> 443, or 80 -> 443 and 443 -> 443, or 80-443 -> 443 I get no connection. The app shows “Website not available” and “net::ERR_FAILED” and the browser shows a big home assistant badge with “retry” below it. It took me hours to figure out it is the damn router which is making the trouble.
I would appreciate any ideas where to look or a hint why this working that way, maybe its supposed to work like that and I am missing something.
Thanks in advance.
