joining freind problems

[JD_gunslinger]

Every time i try to join my friend it says joining game server then stops is there a reason for that.
Also my router has upnp on and it still says disabled and my network is marked as private.

JD_gunslinger uPnP isn't working properly for everyone, seems like it's your case. You should port forward instead as the guide says.
