There are generally two reasons this would fail:

1) You are behind a firewall or proxy which is restricting you from connecting out to the ports 6400-6429.

2) The Amazon servers we use are blocking your ISP or IP.

You can’t check Amazon’s blacklist directly but you can check indirectly whether other services have blacklisted your IP, which is usually a good indicator.

http://whatismyip.com/ will provide your gateway IP address, and then put that address into

    i can at least get online now but the last 3 matches I've done I've been killed never respawned. I wasted my relics buying new things and get kicked out of the match for inactivity. Thanks nor nothing.

    What the heck s going on with my multiplayer either sort it out or refund my money. Not just this I have been stuck on 24 LP forever after unlocking heavy weapon and co.

    This is not worth my time

    As of 1:20 PM Eastern time all I get is error initializing session manager! Me and for other of my friends were kicked out of the multiplayer and we try to reconnect and we all get the same error!

    So I finally decided to buy a year of PS+ so I can play that sweet Uncharted 4 multiplayer I loved in the beta version. It was one of the reasons I happily paid full price for U4.

    But alas, now that I've tried installed, uninstalled, installed, restarted PS4, modem and router, I am at a loss.

    Why can't I play?! Every single time, all I get is "error initializing session manager"!

    Yet EVERY other game I have lets me play online.

    I love all of my Naughty Dog games and buy them day 1 because they're always so perfect and pay so much attention to detail.

    Well, ND, PLEASE pay attention to this detail and help me play online ASAP! PS+ ain't cheap, and U4 MP is really the only I game I want to play.

    Peace, love and thanks,

    Josh F

    I need to have a ps+ account to play uncharted 4 multiplayer??? Beacause when I want to play multiplayer it is connecting and then say You've been disconnected from the Playstation Network.You must been connected to acces the online portions of this title. I am connected to internet and is very good and i make the internet connection and everything was sucesful. Please tell my what to do i have a single account on ps4 .

    Since the new update I've been getting this a lot! I won over 20 matches and didn't get my relics, so I left and restarted to see if it'll give me them and now I can't seem to play at all because of this message. My online is fine, I'm always signed in to the network, and now it won't let me into a game! What the fuck?!?! I know you guys have always had problems with loading and shit but this is beyond a joke, you've made millions off this game!!! WE EXPECT BETTER!!!

    all good when i checked blacklist. I think the reason why multiplayer fail, is number 1. But how can i fix this on my netgear router?
