HTTP Integration not set-up for reverse proxy using traefik

Configuration
1

Hello,

I’m having issues to use Home Assistant running on Docker and using Traefik as reverse proxy.
when I hit the URL defined on Traefik I get an 400: Bad Request error and looking the HASS log I see:

2022-01-09 11:19:59 ERROR (MainThread) [homeassistant.components.http.forwarded] A request from a reverse proxy was received from 172.18.0.4, but your HTTP integration is not set-up for reverse proxies

On the configuration.yaml for home assistant I’ve the following parameters for the HTTP:

http:
use_x_forwarded_for: true
trusted_proxies:
- 172.18.0.0/27 # Internal docker network subnet
- 127.0.0.1

Any idea what could be wrong?

Did you confirm traefik actually sends “x-forwarded-for”?
Lots of results searching those terms…
