This same exact thing is happening with my account. I took a break from the game for a month+, I come back and with what I know are the right credentials I'm Unable to Connect. I connect fine with a second account.
I tried resetting the password via the website, but it says there isn't an account with my e-mail.
Yet, when I try to input login credentials for a non-existing account, it just brings up the "The information you have entered is not valid" message; for my account, whether I enter the right password or not, it goes Authenticating, Handshaking, Unable to connect.
If I were banned, I'd a least be able to tell by logging into the website, but I can't even do that.
Unable to connect, unable to connect, unable to connect.
