PC1 can connect to PC2, but PC2 can't connect to PC1

I don’t know whether I choose right section or no…
I make a network game. I download my packaged game on my laptop. If I create server on the laptop and connect from my desktop computer, so it successfull. But if I create server on my desktop PC, I can’t connect from the laptop. I tried to deactivate anti-virus and firewall. Anyway I get the same result. Why does it occurs?

You could look for the Log files in your Saved folder. There should be a log file with information on why he can’t join.
Either the Log from the Laptop or the one from the desktop should have a log about that.

Often this is due to anti virus and firewall, but you said you already deactivated them :confused:
