The main reason that can cause this issue is the PlayStation servers being down. Make sure that the servers are working correctly by checking the status on the official website. Another cause for this issue could be your own internet connection, so ensure that it doesn’t have any issues. You should also try to change the DNS to see if it is the source of the problem.

3. Set custom DNS from Google
This issue may also be brought on by an inconsistent DNS range, which makes connecting to the server more difficult than it should be. This typically happens with ISPs that use level 3 nodes that are inhibiting automatic port forwarding. Migration of your default DNS (Domain Name Address) range to the Google-supplied range should eliminate the issue and allow your console to communicate with the PlayStation server.
