Login redirection issue with webcpanel on OpenLiteSpeed reverse proxy

[cemalsenturk]

I’m using the webcpanel module with an OpenLiteSpeed web server.
To enable SSL, I created a subdomain and configured a reverse proxy to the port where webcpanel is running.

The login screen loads correctly, but after login the redirection is broken:

Expected:
https://mywebsite.com/nickserv/info

Actual:
https://nickserv/info

If I manually enter the correct URL (https://mywebsite.com/nickserv/info), the panel works as expected. The issue only occurs during the login redirection process.

Question:
Is this caused by my reverse proxy configuration in OpenLiteSpeed, or is it an issue in the webcpanel module itself?

Environment:

Web server: OpenLiteSpeed (with SSL)

Module: webcpanel

Reverse proxy to: 127.0.0.1:8080

I'd guess that OpenLiteSpeed is not sending a Host header so Anope is generating the wrong redirect URL.
