Cannot log in to Nginx when using Access List about nginx-proxy-manager

[TechGuyAlabama]

ok I did find on the website the following:

https://nginxproxymanager.com/faq/#when-adding-username-and-password-access-control-to-a-proxy-host-i-can-no-longer-login-into-the-app

I went this direction, using a username/password, since the ip portion was not working for me. I'll explain.

I work from a dedicated server as a development box that h as a static ip address. I added my ip to ALLOW in the Access List. I did not enter a username or password. When I try to access the website, I get a 403 forbidden.

I tailed the logs and this is what it is showing:

[13/Jun/2024:20:12:23 +0000] - - 403 - GET https nginx.mydomain.com "/" [Client 192.168.48.1] [Length 111] [Gzip 1.35] [Sent-to 192.168.48.4] "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:126.0) Gecko/20100101 Firefox/126.0" "-"
[13/Jun/2024:20:12:23 +0000] - - 403 - GET https nginx.mydomain.com "/" [Client 192.168.48.1] [Length 111] [Gzip 1.35] [Sent-to 192.168.48.4] "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:126.0) Gecko/20100101 Firefox/126.0" "-"

The client that its referring to is the ip of the network gateway that Nginx and MariaDB is currently running on.

I checked SSH to verify the ip address of what it saw my ip address as, and it shows my public ip of my dev server.

I tailed the logs when I connected from my office, which is in another state, and I show the same thing:

[13/Jun/2024:20:23:05 +0000] - - 403 - GET https nginx.tygir.com "/" [Client 192.168.48.1] [Length 111] [Gzip 1.35] [Sent-to 192.168.48.4] "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:127.0) Gecko/20100101 Firefox/127.0" "-"

Any suggestions would be greatly appreciated!
