Server is unstable

Technical Support

  1. Suddenly I was unable to connect to the server (kor).
    pop up message: Failed to connect to Classic Server [Error 3:10]
    After a few minutes I was able to connect to the server.

  2. After some game matches, I frequently see a red error message on channel.[Failed to join channel: Error 4:102. (Error 4:102)]
    And sometimes channel doesn’t open at all. It seems to need maintenance.
