I get this error since long time ago now. I have seriously tried everything at all! I rebooted my computer, I have deleted everything related to the game and uninstalled, re-downloaded and re-installed the game like 10 times (No bs). I checked my firewall and antivirus and everything seems to be fine and also turning them off didn't help. I have used the "ipconfig /flushdns" and the "netsh winsock reset" commands. I have changed the game compatibility configurations. Updated java and directx. But nothing worked at all. Is there any other solution? I doubt it but there must be a last option.
