Why did error NP-31866-4 occur on PS4 and what should I do?

NP-31866-4 on PS4 and PS5 is a network error that appears when the user tries to upload saved data to or from the cloud. The main problem is that you might have important data on the server, but this failure prevents you from getting it. This is especially true for those who switch from PS4 to PS5 and want to save all their data, and there are most of them. Well, we have a couple of powerful ways that just have to work.

What is bug NP-31866-4?

The main reason is that Sony cannot verify the rights to this game and it blocks the procedure, considering the game to be pirated. This behavior may be due to problems connecting to the server due to incorrect password entry, possibly after being asked to reset it. It is also known that the error can appear for those users who have not verified their email. An email with a code or activation link should be sent to the mailbox.

User reviews indicate that the main reason is some kind of problem on the part of Sony or trying to recover the password. This conclusion suggests itself for the reason that most users were helped by changing the main login password. This option is worth trying first.

Something similar needs to be done on the PS4. The required parameter is located in the settings in the “Account Management” section and in the “Account Information” tab. In the column “Security” you can change your password.

Method 2: restore licenses

What do we have to do:

  1. Go to “Settings” on the “Account Management” page.
  2. Click on the item “Restore licenses”.
