Domain server denying my ip.

Not sure if I am posting in the right category.

I am using Drupal 7 for my domain and have several modules added (ubercart,ubercart auction,views,cck, fbconnect, libraries, etc)

Recently I started to be unable to access my website from my computer or even it's cpanel. So I would switch to a back-up router and be able to work on the site for awhile until my hosting server temporarily flagged that ip.
(I know it's the server flagging me because I traced the route to it and I get dumped once it reaches the server in Atlanta)
btw even if I hook straight up to WAN the same thing happens (so not a behind-router problem) - I work on the site for 10 minutes and BAM it goes down for an hour, sometimes longer.

I am suspicious that the problem is with the fbconnect module and it's php sdk library I installed - have also seen similar problems and people blaming it on views. Quite frankly, I have no sweet clue. So... I contacted my host who said that it was a module triggering the firewall but I'd have to figure it out myself through trial and error which one it was.

The reason I ask about fbconnect is because of it accessing external libraries, using Libraries module and the fact 404 errors relating to my unauthenticated users are logged from random facebook accounts. My guess would be that, the server would flag this attempt to "access libraries"

I don't know, I've since disabled fbconnect since the last time I was unflagged, then got flagged again (before getting a chance to delete fb library files as well or disable Libraries), got frustrated and came on here. Thanks for any input in advance.
