Hello I am new to VS and was able to set up a server on my own pc that my friends can play but when I try to join it I get an error message of "no message could be made because the target machine actively refused it". The server works for my buddies but not me, is there something I'm missing about server hosting or do I just need to disable the server and use the open to internet feature when I want to play with my friends?
