My friend got the http cannot connect problem, since the beta opened,we played without any problem but yesterday his connection crashed,when it came back,the probleme was here,even though his connection is faster than before.
We tried everything that were being said but still can't.
Hope that patch of yours will be out soon enough,or anything that would fix this.
Please keep us posted
Edit: He fixed it by reseting everything in the advanced panel in the "internet option" in the control panel (sorry about the direction,mine is in french)
