I just got my problem fixed, the school i go to and live at have had problems with the internet so they had closed some ports in their firewall so i could not log in to Diablo 3, WoW, WoT or WoWS.
Far from good, after a few hours of "Failed to connect to server, Please try again later" i managed to get in and play for an hour then got DC and have been stuck at the login screen since then.
