If you’re having trouble connecting to your PlayStation 4’s DNS server, there may be a few things you can do to help. First, make sure that your PlayStation 4 is up and running. If it isn’t, you can check for updates by going to the PlayStation Network website and clicking on the “Update Your PlayStation 4” link. If you don’t have an internet connection or if your PS4 is out of range of the network, then you can try resetting your DNS server. To do this, open a command prompt and type “nslookup”. After doing this, make sure that your DNS server is set to “localhost”. If it isn’t, then you can try setting it back to “localhost” by typing “setdns”. After doing this, make sure that your PS4 is connected to the network again by checking for updates again and clicking on the “Update Your Playstation 4” link.
