I made a post previous to this with the same issue but I just thought that this might bring more attention to the problem. I see other people are having this issue.
Hello, I just recently installed the 1.12 client and made an account. I was never able to login but immediately got the "Unable to Connect" error followed by a message saying my account has been banned. When logging in, on the first attempt it goes all the way to the "success" message before saying that it was unable to connect. On the next attempts it goes from authenticating straight to my account being closed. I have tried everything recommended, including opening up the recommended ports and making a new account with a shorter password.
Account name is "sotic" and it was determined in a previous post that my account was NOT banned.
Thank you for any help
