Can't host custom game with my friends I tried all
I have the UPnP enabled, I checked my ports in my router and tried everything, I tried changing the default port from 4976 to 4977 and nothing, also I tried to enable all the aplications through the firewall, I put my network profile to private and nothing, also port forwarding and nothing I guess, I don't know if I did it well
@pepsi-con-limon on your second screenshot are you sure that "Internal host" is your PC? Also as the guide says make sure to be in-game to be joined.
If you did all that then maybe that's your issue:
even if you did everything correctly some softwares can still block the connections like your firewall or your antivirus firewall.
