I also can't connect to effnet this past week. The change was abrupt. I have networked computers, and what is strange is i CAN connect on my older computer, no problem...but not on this one. I get error message "Invalid Username'...or 'banned, cached'. I did change the 4 digit port # by one digit and was tmprarily on effnet...but stupidly backed out and cannot get back in now. Is this a problem with my computer?
