I have this connection problem for a while now, namely I get "unable to connect" window every time I try to log in even though my internet connection is fine. I am having the same issue no matter which one of my accounts I try to log. This problem was recurring for the past week, and since 3 days ago I cannot log in at all, I always get "Unable to connect window". I tried contacting support and GMs but none was able (or willing) to help me or at least determine if the issue is coming from my side or theirs, but it started happening after the server restart (the one before 17th of June).
I see I'm not the only one with the same problem, according to many topics opened and unanswered here. But if any of you who had the same problem can tell me how to fix it or at least where the issue originates from I will be very gratefull (hell, I will reward you even).
