Changed the server from "best latency" to "southeast asia" and its ok now.
Tried to connect to China server and got above issue again. Seems something is wrong with the China server.
you can do it on key/login screen
still got issues?
yeah, got same errors whatever using china /sa / us servers,
the difference is using southeast asia server could continue rifting while other regions don't.
It's better. Thanks.is it better now?
