Authenticaion settings for multiple domains

[B08Z]

Good Afternoon.

I have multiple domains that I wish to protect with Authentik (my current Oauth2 provider).
I have set up Oauth2 for my first domain (grafana.domain.uk)
The URL callbacks etc have been added to .env and grafana.domain.uk has been set up in Authentik - all is working.

What I cant work out is how to add another domain in my case an internal one (home.lan, for example)
home.lan is all set up and working but adding details to the .env file has no effect.

If I select enable authentication on the home.lan domain it defaults to grafana.domain.uk, and fails with 404 error.

I have looked at:
Oauth2 Proxy - issue 2140
Oauth 2 Proxy multi whitelist

Hi @B08Z

In Wiredoor, each domain gets its own dedicated oauth2-proxy instance automatically. This means you don’t need to configure multiple domains on a single oauth2-proxy. You only need to set the OAuth2-related environment variables (like OAUTH2_PROXY_CLIENT_ID, OAUTH2_PROXY_PROVIDER, OAUTH2_PROXY_CLIENT_SECRET, etc.) globally in your .env file and Wiredoor handles the rest per domain.

So in your case, once you enable authentication for home.lan, Wiredoor will spin up a separate oauth2-proxy just for that domain (isolated from grafana.domain.uk). If you’re seeing it default back to the Grafana instance, it might be a caching issue or a misconfiguration with the .env variables not being applied correctly. Try restarting the containers after confirming the .env changes.

Let me know if it keeps happening, we can dig into logs or double-check the .env setup together.
