Have the same problem one hour ago and it's resolved ;)
64403
server port 2416
Tried changing port to 2271 but it prompted upon reopening: Login failed due to a wrong username/password combination. If you haven't logged in in a while, it's possible your username was recycled and taken by another user. Please try logging in with a different username and password using the button below, or via the 'Login As' button above the Options->Login tab.
