NP-31730-4
Sony PlayStation
Severity: MinorWhat Does This Error Mean?
The NP-31730-4 error means your PlayStation failed to sync trophies with the PlayStation Network servers. Trophies are the achievement badges you earn while playing games. This error usually happens because of a temporary server hiccup or a slow internet connection.
Affected Models
- PlayStation 4
- PlayStation 4 Slim
- PlayStation 4 Pro
- PlayStation 5
- PlayStation 5 Digital Edition
Common Causes
- PlayStation Network servers are temporarily overloaded or under maintenance
- Your internet connection is too slow or unstable for the sync to complete
- The trophy data on your console has become slightly corrupted
- You are trying to sync a very large number of trophies at once after being offline for a long time
- A network timeout occurred during the sync process
How to Fix It
-
Wait a few minutes and try syncing trophies again. Go to Trophies, press Options, and select 'Sync with PlayStation Network.'
Server-side issues are the most common cause. Waiting a few minutes often fixes it.
-
Check if PlayStation Network is having issues. Visit status.playstation.com on your phone or computer.
If PSN services are listed as having problems, the trophy sync will fail until they are fixed.
-
Test your internet connection. Go to Settings > Network > Test Internet Connection. Check that both 'Internet Connection' and 'PlayStation Network' show as successful.
Trophy sync requires a stable connection to PSN. If the test fails, fix your internet first.
-
Restart your PlayStation and your router. Turn off the console completely, unplug your router for 60 seconds, then turn everything back on.
A fresh connection often clears temporary network glitches that block trophy syncing.
When to Call a Professional
This error does not indicate a hardware problem with your console. It is a network or server issue that almost always resolves on its own. If it persists for more than a few days, contact Sony support to check your account status.
Frequently Asked Questions
Will I lose my trophies if the sync fails?
No. Your trophies are saved locally on your PlayStation first. The sync just uploads them to Sony's servers so they appear on your online profile. Your earned trophies are safe even if the sync keeps failing.
Why do trophies need to sync at all?
Syncing uploads your trophy progress to PlayStation Network's servers. This lets your friends see your trophies and updates your online profile. Without syncing, trophies only exist on your local console.
Can I earn new trophies while the sync is broken?
Yes. You can keep playing and earning trophies normally. They will be saved on your console. Once the sync issue is resolved, all your new trophies will upload together.
