NGINX proxyauth documentation is incorrect #423

Describe the bug:

The documentation says:

  # url to send auth_request. Should be ${APP_URL}/api/authz/auth-request
  proxy_pass http://voidauth:3000/api/authz/auth-request;

So I did use the URL I set in my voidauth APP_URL config, meaning I used:

 proxy_pass https://auth.mydomain.com/api/authz/auth-request;

This caused a 500 error

However if I use the internal voidauth url (ie: http://127.0.0.1:3000/api/authz/auth-request; ) , it works

I'm assuming the documentation is wrong

Additional context:

Good job, other than that, this was super easy to setup compared to Authentik, hopefully a security audit happen soon so that it's safe to use for stuff exposed to the internet :)
