PlayStation Error NP-31726-3 — What It Means & How to Fix It

What Does This Error Mean?

NP-31726-3 means your PlayStation 4 failed to connect to the PlayStation Network (PSN) servers. The console reached your router but the connection to Sony's servers timed out or was refused. This is often a temporary PSN outage or a home network configuration problem. Most cases resolve quickly with a few simple steps.

Affected Models

PlayStation 4
PlayStation 4 Slim
PlayStation 4 Pro

Common Causes

PlayStation Network (PSN) is temporarily down for maintenance or experiencing high traffic
Your router's DNS settings are slow or incorrectly configured for gaming
Strict NAT type on your router preventing a stable connection to PSN
Wi-Fi signal too weak or unstable for a reliable PSN connection
Outdated PS4 system software causing compatibility issues with PSN servers

How to Fix It

Check PSN server status first. Go to status.playstation.com on your phone or computer. If PSN is down for maintenance, you simply have to wait — no fix on your end will help.

PSN maintenance is usually scheduled overnight. Check the status page before troubleshooting your own network.
Restart your modem and router. Unplug both from power, wait 30 seconds, plug the modem in first, wait 1 minute, then plug in the router. Wait another minute before testing.

A fresh router restart often resolves connection issues that have developed over days of continuous operation.
On your PS4, go to Settings > Network > Test Internet Connection and note your NAT Type. If it shows NAT Type 3 (Strict), your router is blocking some PSN connections.

NAT Type 2 (Moderate) is acceptable. NAT Type 1 (Open) is ideal. NAT Type 3 causes frequent disconnections and errors like NP-31726-3.
Change your PS4 DNS to use faster, gaming-friendly servers. Go to Settings > Network > Set Up Internet Connection > Custom. Set Primary DNS to 8.8.8.8 and Secondary DNS to 8.8.4.4 (Google's servers).

Changing DNS is free, safe, and often dramatically improves PSN connection stability.
Go to Settings > System Software Update and install any available updates. Outdated PS4 firmware can cause connection compatibility issues with Sony's current PSN infrastructure.

Keep your PS4 set to download updates automatically so this is never a problem.

When to Call a Professional

NP-31726-3 is almost always a self-service fix — no professional service needed. Check PSN status, restart your router, and update your PS4 system software. If your NAT type is Strict and you cannot change it, your ISP may need to be involved.

Frequently Asked Questions

Why does NP-31726-3 only happen at certain times of day?

PSN experiences heavy traffic during evenings and weekends when millions of players are online simultaneously. This can cause temporary connection failures that only happen during peak hours. If NP-31726-3 consistently appears in the evenings, PSN congestion is the most likely cause.

Is my PS4 broken if I see NP-31726-3?

No. NP-31726-3 is a network error, not a hardware fault. Your PS4 is working fine — it simply cannot reach PSN at that moment. You can still play downloaded games offline while the connection issue persists.

Will using a wired Ethernet cable instead of Wi-Fi help?

Yes, often significantly. A wired connection is more stable and faster than Wi-Fi. If NP-31726-3 happens frequently over Wi-Fi, a wired Ethernet connection between your PS4 and router will reduce or eliminate the issue.
