Your account probably isn't ok. I didn't get disconnected because I hadn't been on in a few days but I tried to log on and my account was banned. I posted an appeal and a GM answered me saying "Your account was compromised and used for gold spam." And literally nothing else. I am still waiting on a response on whether or not I can get unbanned, but for some reason it seems to take a minimum of 12-24 hours to get a response.
The same thing most likely happened to you and even though we have done nothing wrong and do not deserve to be banned we are being punished. I would say post in ban appeals and wait for a reply, hopefully they will unban you, I am still waiting on a reply to my 2nd ban appeal.
good luck
