So me and my best friends have been playing Uncharted together since 2. After a while we couldn't join each others parties. The only way we could play together was if someone else was there, acting as a 'medium'. This problem still exists for is in Uncharted 3. No matter what we do or how many times we reboot our systems and games, we can't join each other. We tried matching NAT types, still doesn't work. We would like to be able to join each others parties without the hassle of asking someone else to host. Also, this happens to me with ransoms too. Just yesterday I made a friend on PSN through UC3 and we added each other and when we tried to join each others lobbies it wouldn't work. Our names would flicker in the other persons lobby for a second, then it would say 'Unable to join party'. I really would like to know if there is anything I can do to fix this. I love Uncharted and would really like to enjoy the Multiplayer with my friends.
Try a different game. Happened to me, we all went to COD: BO zombies and could just play fine. Other than that you could try reading this if you don't understand some things.
Than you can attempt this.
It means that you need a player that has Best Connection To host the party. From there say you have 3 people in total, 2 others have to join the host. 1 of the 2 have a chance of being removed from the party. You have to figure out the pattern, whether its person A, Or B, who joins first, vice versa. A player joining might cause the other player to not be able to join, or get removed.
I know this is an old message, but it's still a current problem, as it happened to me and a friend. Luckily It's easy to fix!
Simply make a note of the players name from your friends list that you are 'unable to join party' with, then delete them.
Send out a new friend request to them using 'add friend' from the PS menu...This will now fix the problem!
I don't know if it'is a permanent fix, but it's been working fine for me and my friend since doing this
The simple way is to make another player the party leader(who is not having this trouble) you and youre friend can join his party without any troubles it helps me too !! with my friend and its a simple answer you can try it out , it should really work.
Second, he's saying that he prefers NOT to have a medium. Meaning, just them. No third wheeler,
I had this problem too, both in Uncharted 2 and Uncharted 4,try this....
When 'unable to join party' pops up, you should both quit uncharted 3(or go directly) > XMB > Network Connection > Internet Connection Test. Once you both have completed a Internet connection test, go back in to uncharted 2 or 3, play multiplayer and you SHOULD be able to join your friends party. I don't know WHY this works, but trust me it does, as me and friend did it MANY times, and it was always our go to solution for when we couldn't party up together.
I never understood how im not changing any of my settings, neither is he, but after doing the Internet connection test, we are somehow able to party up. It's bizzare but it works for me, even if it's a bit lengthy. Hope it helps you too
