PlayStation Error Code CE-32937-4 — What It Means & How to Fix It

What Does This Error Mean?

CE-32937-4 means your PlayStation failed to connect to the PlayStation Network (PSN). This blocks you from signing in, playing online, or accessing the PlayStation Store. It is usually caused by a network issue on your side or a temporary PSN outage.

Affected Models

PlayStation 4
PlayStation 4 Slim
PlayStation 4 Pro

Common Causes

PlayStation Network is down for scheduled maintenance or experiencing an outage
Your home internet connection has dropped or is unstable
Your router or modem needs to be restarted to refresh the connection
Your PS4 network settings have become outdated or misconfigured
Your router's firewall or NAT settings are blocking the connection to PSN servers

How to Fix It

Check the PSN status page. On your phone or computer, go to status.playstation.com and look for any reported outages.

If PSN is down, there is nothing to do but wait. Sony usually resolves outages within a few hours.
Restart your PS4 completely. Press and hold the PS button, select Power, and choose Restart PS4.

A full restart clears the network cache and re-establishes the connection from scratch.
Restart your router and modem. Unplug both from power, wait 60 seconds, plug in the modem first, wait for it to connect, then plug in the router.

This refreshes your IP address and clears any stuck routing issues.
Run a network test on the PS4. Go to Settings > Network > Test Internet Connection. Note if any step fails.

This will show exactly where the connection breaks — internet, PSN sign-in, or NAT type.
Change your DNS settings. Go to Settings > Network > Set Up Internet Connection. Use Custom setup and enter 8.8.8.8 as primary DNS and 8.8.4.4 as secondary.

Using Google's DNS is often faster and more reliable than your internet provider's default DNS.

When to Call a Professional

Frequently Asked Questions

How do I know if PSN is down and not my internet?

Go to status.playstation.com on your phone while using mobile data (not your home Wi-Fi). If PSN shows green but your PS4 still cannot connect, the issue is on your home network. If PSN shows issues, the problem is on Sony's end and you just need to wait.

What NAT type should my PS4 have?

NAT Type 2 is the recommended setting for PS4. NAT Type 1 is ideal but requires a direct connection. NAT Type 3 means your router is heavily restricted — this can prevent PSN connections. Check your router settings and enable UPnP if your NAT type is 3.

Will changing DNS settings affect anything else on my network?

Changing DNS only affects your PS4's DNS lookups — it does not impact other devices. Google's DNS (8.8.8.8) is safe, fast, and widely trusted. If you experience any issues after the change, you can always go back to Automatic DNS in the same settings menu.
