Port 80 not being redirected (help setting up reverse proxy for immich server)

[spacecase-25]

One thing to note, I am on the LAN at the moment.

However, I have installed nginx proxy manager on a LAN server (192.188.0.2) and have forwarded ports 80 and 443 via NAT.  But, if I go to subdomain.domain, rather than this traffic being forwarded to the proxy server and then further redirected to the appropriate server & port (192.188.0.2:2283) I am prompted to log into the router. 

How do I get the results I am looking for?

EDIT: Just had a buddy test and it is not working properly from outside the LAN either.



EDIT2:  Let's just cut to the chase here... can someone tell me how to get reverse proxy working so that I can access my immich server?  That's what I'm trying to do.

Did you move the web UI to a different port like e.g. 4443 and disable the HTTP -- HTTPS redirection?

Yes, but still does not work.  I'm no longer getting a log in prompt, now I just get nothing.
