Is it possible that in the Manager and then log in for the Gateway Server, if we select “Random” and then when logging 2 char the once. Condition is like checking the gateway server is used by the login.
If char 1 login using the gateway server = 220.127.116.11 and then the char 2 auto select the other gateway server to avoid login them at the same gateway server.
From my experience, if I’m using Random the 2 char will log in to queue the same gateway server when they login to the game automatically banned my IP. I ve always encounter this problem they will logged same gateway server at the same time.
