Login attempt with invalid authentication (Nginx + Authentik + Homeassistant) #300

Aqui1us · 2024-01-27T18:14:33Z

Hi I'm running Homeassistant as well as Authentik and nginx as Docker containers and want so acces Homeassistant via the nginx reverse proxy using the authentik Auth.

When I use hass2.mysdomain.com (wich is set up in nginx) i get redirected to the Authentik login. So far so good.
After Signing in I get redicrectet to Homeassistant where this error pops up.

The Homeassistant log states:
Login attempt or request with invalid authentication from 192.168.178.101 (192.168.178.101). Requested URL: '/auth/token'

Any help on how to tackle this problem would be appreciated,
I suspect Homeassistant doesn't like the way Authentik hands over the auth_header?
Do i need to add or modify the '/auth/token' somewhere?

did you get it working? I#m having the same issue.

nope, I shelved the project for now.

hahnet · 2024-04-25T21:07:21Z

Solution is to add:

proxy_set_header Host $host;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";

to the config
#236
