nginx, authentik and homeassistant

[katonagl]

I have nginx-pmplus, authentik and homeassistant running on the same server as docker containers. I have tried to follow the description at https://docs.goauthentik.io/integrations/services/home-assistant/. I have installed hass-auth-header, but I am stuck.
I have a proxy host in nginx-pmplus pointing to homeassistant: home.company
I also have a proxy host in nginx-pmplus pointing to authentik: auth.company

Nginx-pmplus, Authentik and homeassistant are in the same docker network: 172.18.0.0/24

The server has a LAN address of 192.168.100.64, ports 8123, 9000 and 9443 are open. I have tried to setup without nginx involved, but did not succeed, authentik was not opened when accessing 192.168.100.64:8123 to authenticate.

How should I setup these to be able to reach homeassistant at home.company after authenticating with authentik?

It was a mistake with nginx config, now it is working, however not exactly according to the linked description.
