Stuck at Unable to connect to Home Assistant

[cyndane31]

I'm able to connect to HASS just fine using a standard NPM reverse proxy setup. Once I introduce the authentik and auth-header bits, I get stuck at the wonderful Unable to connect to Home Assistant screen. I am unfortunately fairly new to this and am afraid I'm missing something obvious. My authentik username and HASS username are identical and TOTP is disabled in HASS

Authentik user:

HASS user:

configuration.yaml

auth_header.yaml

http.yaml

192.168.10.10 is my Nginx Proxy Manager
192.168.10.3 is my Docker instance running Authentik

Debug Log entries: (whitespace added by me for clarity)

@cyndane31 did you ever get this fixed? I'm experiencing similar.
