Authentication debugging - v4.1.4 - Ubuntu 24.04 + nginx

[mbyrdap]

I'm not entirely sure what happened, but running the dev server, I was able to create a superuser and login. After adding nginx as the reverse proxy, I'm getting invalid credentials. I've created new superusers after integrating nginx without issue and none of them will authenticate either. I'm copying a password from a password manager so it's not a typo.

Any help is appreciated.
