PlayStation Error Code WS-37397-9 — What It Means & How to Fix It

What Does This Error Mean?

The WS-37397-9 error means your PlayStation is having trouble connecting to the PlayStation Network. This is usually a network-related issue on Sony's end or with your internet connection. It can also appear if your IP address has been flagged or restricted by Sony.

Affected Models

PlayStation 4
PlayStation 4 Slim
PlayStation 4 Pro
PlayStation 5
PlayStation 5 Digital Edition

Common Causes

The PlayStation Network servers are experiencing downtime or heavy traffic
Your internet connection is unstable or too slow to maintain a connection to PSN
Your IP address has been temporarily flagged by Sony's security systems
Your router's firewall or security settings are blocking PSN connections
A VPN or proxy service is interfering with the connection to Sony's servers

How to Fix It

Check if PSN is down for everyone. Visit the PlayStation Network status page at status.playstation.com on your phone or computer.

If PSN shows outages, you just need to wait. There is nothing you can fix on your end during server downtime.
Restart your router and modem. Unplug them from power, wait 30 seconds, then plug the modem in first, followed by the router.

This refreshes your internet connection and often resolves temporary network glitches.
On your PlayStation, go to Settings > Network > Test Internet Connection. Check that your NAT Type is Type 1 or Type 2.

NAT Type 3 can cause connection problems with PSN. You may need to enable UPnP on your router.
If you are using a VPN, proxy, or custom DNS, disable them temporarily and try connecting with your default internet settings.

Sony sometimes blocks connections that come through VPNs or proxies for security reasons.
Try connecting your PlayStation directly to your router with an ethernet cable instead of Wi-Fi.

A wired connection is more stable and eliminates Wi-Fi interference as a possible cause.

When to Call a Professional

This error rarely requires professional help. If PSN is working for others but not for you after trying all steps, contact your internet service provider. They can check if any ports or connections are being blocked on their end. You can also contact PlayStation Support at 1-800-345-7669 for account-specific issues.

Frequently Asked Questions

Does WS-37397-9 mean I am banned from PSN?

Not necessarily. This error is usually caused by server issues or network problems. However, if your account has been suspended, you may see this error when trying to sign in. Check your email for any suspension notices from Sony.

How long do PSN outages usually last?

Most PSN outages are resolved within a few hours. Major outages during holiday seasons or big game launches may last longer. Check status.playstation.com for real-time updates on service restoration.

Why does this error happen more on Wi-Fi than ethernet?

Wi-Fi connections are less stable than wired connections. Interference from other devices, walls, and distance from the router can cause drops. A wired ethernet connection provides a consistent, reliable link to your router.
