for some reason i can not join one of my friends and they cannot join me, we can both join other peoples worlds, and servers at the same time but when we try to connect to each other its always says "Unable to connect to multiplayer game" we have both redownloaded Minecraft and just don't know what to do. this has been like this for the past 2 updates, please help. we have tried using VPN to join and switching to different Wi-Fi networks.
