port server?
nah.
I think you're referring to the port forwarding you have to do to run a server but you don't need to do that to run the game.
whenever you're making a server of this nature, you must allow the connections into your computer, however for a client like you thats not the case
unless your computer somehow works so that you have to do something like that (which I've never heard) of, then it's most likely your firewall
idk how to help because I don't know what you mean by this port stuff so
yeah
