ACL on Proxy Host for Nginx Proxy Manager Administration Does Not Auth

[jiriteach]

Checklist

• Have you pulled and found the error with jc21/nginx-proxy-manager:latest docker image? Yes

• Are you sure you're not using someone else's docker image? Yes

• If having problems with Lets Encrypt, have you made absolutely sure your site is accessible from outside of your network? N/A

Describe the bug I have a proxy host setup to NPM administration. e.g. abc.domain.com --> proxy host to NPM:81. This is working fine. I would like to add an ACL with HTTP basic auth in-front of the NPM login screen. Doing so causes auth to prompt but credentials do not work on Chrome or Firefox. Seems to work on Safari.

• What version of Nginx Proxy Manager is reported on the login page? 2.7.2 (which is a bug since 2.7.3 is installed)

To Reproduce

1. Create a proxy host rule to NPM administration.
2. Add an access list to the proxy host rule.
3. Test on Google Chrome or Firefox.

Expected behavior Auth to success and show the NPM administration login screen.

Operating System NPM is running on a RPI4 via Docker. Browsers have been tested on both MacOS and Windows.

I can confirm this issue aswell, same rasspberry pi setup. For me at least, it just keeps in locked in the authentication prompts and never lets me get to the manager, similar to #843

I have my reproxy host access list setup where it authenticates with my username and password, and it checks to see if Im logging in from my network's public address. Even odder is that I have to have Satisfy any enabled or else I get sent to a 403 error.

I have a simliar issue however on mobile i get through the auth pop up the first time (chrome/safari), I also can get through the first time around when using safari on mac. When using the desktop version of chrome/brave/firefox it just loops. I noticed that if i login once in the auth pop up and leave it there for lets say 5-10 mins it eventually goes through.

I am having a similar issue. I can get past the HTTP auth prompt, but then it won't accept my username and password.
It simply says Unauthorized. under the password field.

Just ran into this problem too. I had to enable the port 81 again to be able to login directly and remove the acl and be able to use it again.

Same issue on Ubuntu 20.04, specifically when IP + user is enabled in ACL. Works fine for redirection hosts but not for proxy hosts.
