HTTP integration is not set-up for reverse proxies

[gatonero]

Vielen Dank für diese Anleitung!

Bei dem ersten Aufruf von http://localhost erhalte ich "400: Bad Request" und finde in den Logs folgenden Eintrag:

`Running as 1000:1000

Initializing venv in /var/tmp/venv

Starting homeassistant

2023-02-09 12:36:57.382 ERROR (MainThread) [homeassistant.components.http.forwarded] A request from a reverse proxy was received from 172.26.0.2, but your HTTP integration is not set-up for reverse proxies`

In meinem LAN befindet sich ein reverse proxy. Aber der sollte bei einem Zugriff auf localhost doch keine Rolle spielen?

Hi @gatonero

this is not about a regular proxy device that you'd use in your LAN to protect your access the internet. A 'reverse-proxy' means a service 'inside a server' that takes incoming HTTP requests and does some filtering, before handing them to another service that actually handles those HTTP requests.

-- PC or handi --            -------    Home Assistant Docker   ------        
     Browser                  Apache daemon           Home Assistant
  HTTP request      ---->    Add HTTPS certs  --->  Serve HTTP content

so from you Browser client, on a different device, you don't but localhost but you need to put the hostname or address of the device running Home Assistant Docker
e.g. http://mydockerdevice/ or http://192.168.1.56/

Other than that, it is quite possible that your Home Assistant settings for http integration have some missing settings. Home Assistant has moved on lots since the version I last tested with this, and you may need some additional 'configuration.yaml' style settings. See the example in https://community.home-assistant.io/t/http-integration-is-not-set-up-for-reverse-proxies/313284/5 (although this uses a plugin that you may not have).

Guten glück

Thanks a lot. I will continue to fiddle around and take your steps as a template.

Sure, @gatonero , you can fork the project then change what you need in your own fork and keep only the useful bits from here. Enjoy!

Hi again @gatonero I have uploaded commit 65a1ab4 which should deal with this issue. It may be a little late for you, but it's there for others. Thanks for warning about this.
