Facebook Connect error

Hi there,

Having a pretty standard problem: I can't login via Facebook. When I run the CP's Integration Test I get this:

Your server could not connect to Facebook (https://graph.facebook.com). Try again later. If the issue persists, contact your host.
I've searched around a bit and it seems a number of users have run into this, and the problem is almost invariably solved by Mike asking for their FTP information and checking on some server settings. So...how about it, Mike? :D
