app proxy for home assistant 400

[eyecreate]

When trying to have an App Proxy set up to proxy my local HomeAssistant to be available on a domain, after logging in to cloudron on the domain it only gives 400 error. Is this a cloudron setup issue or issue with HomeAssistant? I use http for uri and use ipv4 address with port. I'm unable to see anything in proxy app logs.

@eyecreate have you updated your homeassistant configuration.yaml file to add your cloudron IP as a trusted reverse proxy IP?

Is there any other information available like the message sent with the 400 to somehow get any clue who is sending that?

@nebulon this is all I have:

@hakunamatata good call! I didn't guess they would only allow a list of proxy sources. Now the proxy works well!

Glad to hear that you got it working! By the way, have you had any luck logging into the HomeAssistant companion app (iOS in my case) using the proxied domain?
