The FIEF_DOMAIN is not used when redirecting auth requests for the admin page.

Describe the bug

When fief is redirecting back from the login page, to the admin page, it uses the local ip address instead of the FIEF_DOMAIN. I'm using nginx as a reverse proxy and i get the message "redirect_uri is not authorized for this client"

I'm a bit unsure if i'm doing something wrong, but this is the admin panel it comes with.

To Reproduce

Steps to reproduce the behavior:

Used the docker compose below
goto auth.example.test
login
get "redirect_uri is not authorized for this client"

Expected behavior

The redirect would use the FIEF_DOMAIN

Configuration
