Hello we have 3 ps4s in house and I cannot join the party of th either two players. This is third straight night. What can be the issue.
Hey mondragon8183,
It's probably due to all being on the same network. Do you have 2 access points on your network like one of them being a 5GHz option? You could try making sure you only have 2 of you connected to that and the other connected to the standard connection.
Or you can try having 1 person plugged in directly to the router if you are currently all on wireless.
Another option you can try is tethering your PS4 to a mobile hotspot and then try and connect. If it works, then it is likely due to something with the connection and having 3 people on the same thing, it can cause issues like this.
You may also find that it affects someone else if you invite them to a party instead of you trying to join theirs, it may stop one of them connecting to you.
