Solution 1. Set internet protocol (IP) address and domain name system (DNS) to Manual

“PS4 error NW-31456-9” may appear when your PS4 is blocked by a firewall or your network configuration is not stable. You may want to try other DNS server such as Google Public DNS or call your internet service provider (ISP), if they could provide you with a DNS. Changing your DNS server may bypass firewall setting on your home network. Please see below.

Also, since you are accessing PS4 Network Setting, you may want to set your PS4 IP address to static. Doing this could make your connection stable.

To know the range of your home network IP address, go to “View connection” copy the current IP address.  You may also want to increase your IP address’ last three digits to avoid conflict it with other devices.

To set PS4 IP address and domain name system (DNS) using the router watch this YouTube video here.

If the issue persists, the firewall could be set in your router you are using. You may want to directly connect your PS4 to your modem.
