I'm having the same error, but only with 1 person, I have 2 alternative characters and with them can connect without any problem, until I mark that my connection is excellent, but when connecting with my main character disconnects me with error 90006 O 90002. I really do not think that my internet connection error because of how I explain that one character can connect and another can not. I have already done the report of an SE but it seems that it does not matter because of the problems of the users
