Enable both cloud & local access | Home Assistant | Page 1

#

Hey,

I have Home Assistant Cloud, and am currently using homeassistant with the configured cloud hostname, we'll say "cloud.example.com". I also currently have, pointing to my home assistant, "home.example.com" with the nginx add-in proxying it back to home assistant.

However, I'm getting permission errors returned when the nginx proxy attempts to connect:

2025/08/02 14:47:09 [error] 128#128: *734 connect() failed (111: Connection refused) while connecting to upstream, client: [my lan ip], server: home.example.com, request: "GET / HTTP/2.0", upstream: "http://172.30.32.1:8123/", host: "home.example.com"

I'll note I have the entire 172.16/12 RFC 1918 range in allowed_proxies (along with 127.0.0.1)

I'm wondering:

If I need to configure nginx to rewrite the host header from "home.example.com" to "cloud.example.com"
If it's not possible to use the cloud frontend and local https at the same time
I've misconfigured something completely unrelated

Thanks!

Well, updating my own thought, it's connection refused which means definitionally we're not getting to the point of even passing a host. I've verified via ha core info that is the IP address for the ha core container it's using as the backend.

#

The end-state-goal is that I can use http://cloud.example.com and https://home.example.com interchangably (with cloud.example.com CNAME [blah].ui.nabu.casa and home.example.com pointing to mydynamicdnsname.example2.com).
