The PSN is an important part of the PS4 console. PlayStation’s multiplayer infrastructure is built on the PSN and it is very important that you keep logged into the network.

But sometimes things can go wrong. From frequent network failures to just not being able to connect to the PSN, there are so many errors that can occur.

The NP-31730-4  is one such error in the PS4 and today we are going to fix this error for you. So, let us get started.

Reasons for NP-31730-4 Error Code

Mistaken Log Out

The main reason for the NP-31730-4 error is that the user has logged out of the PSN network. If that is the case then, the fix is also pretty straightforward. Simply, log in again and you will be good to go.

PSN is down

Sometimes, this error can occur when the actual PSN is down. This happens when the server is overloaded and you will not be able to connect to the PSN network. The server can also have a maintenance date and this can also cause the error.

PSN ID Hacked

If someone has hacked your PSN ID and changed the password, you won’t be able to log back in. In this case, you need to contact PlayStation and seek help from them. It’s also safe to contact your bank if you had your credit card detail stolen.
