*Make sure it is allowed by Firewall
*Port forward.
*Correct NLoginPort
*Source code.
In your source maybe you put this code in s_NetClient.cpp m_nClientNetState != NET_STATE_FIELD just remove this code.
Hello sir dheluxe, all ports are now forwarded, it is all now open. I already have also exemption on firewall, both file and ports. the nLoginPort on source code is now the same with my cfg ports and param ports. and in s_NetClient.cpp file on source, I dont have this code m_nClientNetState != NET_STATE_FIELD.
I was able to open the game, but when selecting channel number, when click the connect button, the "server connection failed" shows up.
