It points to the console’s cloud-save service—not, by itself, a failed hard drive or other hardware fault. Check your PlayStation Plus eligibility and cloud-storage limits, then work through Sony’s recommended account and console steps.
What NP-31866-4 means
Sony describes NP-31866-4 as “There was an issue with saved data in online storage.” On PS4, online storage is the PlayStation Plus cloud-save feature. Sony says a PlayStation Plus subscription is required to use it. The code does not establish that a local save is damaged or that the console has a hardware problem.
How to fix NP-31866-4
Follow Sony’s checks in order. The support page does not identify one guaranteed cause or promise that a specific step will resolve the error.
- Check your PlayStation Plus subscription. Sign in to PlayStation Store, select your account avatar, then open Subscriptions Management. Confirm that PlayStation Plus is active.
- Restart the PS4. Restart the console, then try the online-storage action again.
- Check your cloud-storage limits. Sony’s PS4 limit is 100 GB and no more than 1,000 saved-data files in online storage. If either limit is exceeded, make room before trying again.
- Sign out and back in. On the PS4, go to Settings > Account Management, sign out, then sign in again.
- Activate the console as your primary PS4. Go to Settings > Account Management > Activate as Your Primary PS4 and follow the on-screen instructions.
If the error remains after these checks, contact PlayStation Support. Sony’s code-specific guidance does not recommend a factory reset or buying replacement hardware as a remedy.

Upload, download, and manage PS4 cloud saves
If you need to transfer a save manually, use the specific action for the direction you want. These are separate operations: uploading sends the system-storage save to online storage; downloading brings an online save to system storage.
- Upload: Settings > Application Data Management > Saved Data in System Storage > Upload to Online Storage.
- Download: Settings > Application Data Management > Saved Data in Online Storage > Download to System Storage.
- Delete an online save: Sony provides deletion through its online-storage saved-data menu. Check which copy you are selecting before deleting; removal of the selected cloud data should not be treated as a routine troubleshooting step.
Enable automatic uploads
Automatic uploads can send saved data from your primary PS4 to online storage. To enable them, go to Settings > Power Saving Settings > Set Features Available in Rest Mode and turn on Stay Connected to the Internet. Then go to Settings > Application Data Management > Auto-Upload and enable automatic uploads. Menu wording may vary slightly with system language or region.
