My b2evolution Version: 4.1.x

We are running 4.1.4. Our url is http://www.uleth.ca/lib/communities/index.php.

Is there a way to stop b2evo from trying to be smarter than our reverse proxy? Our website is reverse proxied from www.uleth.ca/lib to xxx/lib*. The blog side works fine but when you try to do anything on the admin side of the server, you go into an endless loop. Any help would be appreciated.

Right now we can either have our website allow people to see things or we can set it up so that you can login to the admin side but not going through the reverse proxy in the _basic_config.php file settings.
