  • This error only occurs when both my son and I are running both our pcs on my IP…so ultimately I totally cannot play mw2 with my son..which is why I bought it…this really sucks IW…

    • Agree, this is also the case for me and my son. We cannot play the game at the same time. We have bought the game separately and we do not understand why we cannot play. We have tried a bunch of things suggested to us, nothing helps. Seems as if Activision is not looking into this matter, can’t see why we should buy this game again.

      • Just an update, maybe it can help others as well.
        We have managed a couple of times to play together without the game kicking one of us out.
        Did this the both of us:
        – one of us is connecting through cable and the other one through wifi
        – opened CMD through the Windows search, release ip-adress by using ipconfig/release
        – the one with the cable then uses ipconfig/renew , the one with the wifi just waits for it to renew by itself
        – then we start the game at the same time and we’ve managed to play together.
        Dont know if it is important to start the game at the same time, but thats what we do.
        Happy holidays!

    • Hi Cosmic, thanks for replying. There is no official fix for this issue, trust me, I looked everywhere. All of these fixes may work for you however it is not guaranteed. Truly sorry that I can’t help you more. All I can say is that it is worth a shot.

    • I did the hard reboot on my PS5, turning off the whole thing, pulling the power cord from the back of the ps5 and leaving it unplugged for like 10 minutes and then plugged it back in and started it up and so far it is working.

  • Hey guys
    I just had the same issue and i just restarted my playstation 4. And it worked without Problem.
    Hope it works for everybody
