Set Up Port Forwarding for Your PS4
If the above steps don’t fix the problem, you may have to dive into your wireless router and set a forward port for your PS4. We mentioned these steps in the section above, but here’s a more detailed breakdown of the process:
Step 1: Grab the IP Address, Username, and Password for your wireless router. The methods of accessing this information may vary based on your model, but you should be able to access it via a web browser or just by looking at the back of your router (if all of that information is set to the default).
Step 2: Enter your IP Address into a web browser. You should then be able to manually log-in to your router.
Step 3: You should then see a command related to port forwarding. This section will usually include some variation of the words “port” and “forwarding,” but you may need to check your router’s instructions if you don’t see an obvious variation.
Step 4: You’ll then need to add some custom forwarding ports. This can be a bit tricky, but as we said above, some of the recommended ports are 80(TCP), 443(TCP), 3478(TCP and UDP), 3479(TCP and UDP), and 3480(TCP). You’ll then need to register your PS4 IP address to each of these ports. You can consult the guide above for where to find that information if you don’t already have it. Save your changes once you’ve added this information.
Step 5: Go back to your PS4 and open Settings. From there, navigate to Network and Test Internet Connection to see if everything is working properly. Of course, the best way to test this is to try playing a game and see if the error is corrected.
It should also be noted that, if this doesn’t work, you can try enabling Universal Plug and Play (UPnP) on your router. You can find instructions on how to do that in the “How To Change Your PS4 NAT Type” section of this guide.
You can also enable the DMZ setting as we advised you not to do in that same section. Again, there are serious risks associated with this method that you may not want to make yourself vulnerable to.
