The European server is currently refusing connections to most users. Attempting to connect several times MAY allow you to connect, however slow speeds may be the result. An emergency maintenance windowhas been opened for repair. We do not have an exact estimated time for a fix, however you may connect to the US server in the mean time...please check back here for new updates to the ongoing status. We apologize for the downtime and appreciate your patience.
EDIT-- The US server seems to be acting up as well with the authentication errors. Please stand by for further information.
