Can't play! Error Code: HS:NGRESULT DB ERROR:303:0

I’ve tried on two different devices and both give the same error message (HS:NGRESULT DB ERROR:303:0), so the game disconnect. There’re 2 days already, what can I do?

It works if I play in another server.


There is a long topic dealing specifically with that error code here:
