Thread:Project:Support desk/MediaWiki Running Behind Proxy "Unable to determine IP" Error/reply

Had a similar issue where I'm running php through a proxy and have a frontend serving static files. This means mediawiki always sees the REMOTE_ADDR as 127.0.0.1. I was able to fix it by adding this to the end of my LocalSettings.php:

$_SERVER['REMOTE_ADDR'] = $_SERVER['HTTP_X_FORWARDED_FOR'];

It sounds like the root problem is the same, so perhaps this will work for you as well.
