How to Fix PlayStation Error Code WS-37397-9 [Solved]

by

PlayStation Error Code WS-37397-9 is a critical connection rejection failure that occurs when the network authentication servers temporarily black-list your home router’s IP address. This security block completely disconnects your console from the PlayStation Network, tracking your user account into a permanent sign-in failure loop that locks you out of multiplayer lobbies, digital game libraries, and the PlayStation Store.

Whether this network lockout is triggered by your local internet service provider assigning a stale, flag-marked IP profile to your modem or an automated security wall mismatch on Sony’s infrastructure, you can clear it. Follow this step-by-step troubleshooting guide to bypass error WS-37397-9 and restore your console connection immediately.

Common Causes of Error Code WS-37397-9

• Black-listed Router IP Address: Your internet provider assigning a recycled IP tracking profile that triggers Sony’s security walls.
• Congested Network Gateway Nodes: Crowded data traffic pathways at your local connection terminal dropping handshake packets.
• Stale Home Router Cache Logs: Fragmented temporary memory allocation scripts inside your home router forcing connection blocks.

Method 1: Force Your Internet Provider to Assign a Fresh Public IP Profile

If your home internet environment uses a standard dynamic tracking setup, forcing your network hardware to remain offline for a set time will command your internet service provider to clear your old identity block and grant your home network a brand-new IP address.

  1. Turn off your console completely and unplug the power cables directly from the back of your internet modem and wireless router.
  2. Leave all home networking hardware completely disconnected from the wall power outlets for 15 to 20 full minutes.
  3. Plug your internet modem back into the wall outlet first and allow its status light indicators to turn completely solid.
  4. Plug your wireless router back into the power source and wait 2 additional minutes for the wireless network to fully deploy.
  5. Boot your console up, open your network options dashboard layout, and test the internet connection link.

Method 2: Manually Reconfigure Your Console Connection to Use Custom Public DNS

When default internet service provider routing pathways encounter severe packet drop loops, switching your console interface to navigate through independent public pathways bypasses the blocked data tunnels.

  1. Turn on your consoleNormally, navigate to the main dashboard menu layout screen, and open the Settings cog icon.
  2. Select Network from the configuration choices and choose Set Up Internet Connection from the sub-menu layout panel.
  3. Highlight your active home wireless network profile, click the Options button on your controller, and select Advanced Settings.
  4. Locate the DNS Settings line entry, switch the parameter selection from Automatic to Manual, and input these custom public values:
    • Primary DNS: 8.8.8.8
    • Secondary DNS: 8.8.4.4
  5. Select OK to save your newly deployed configuration layout and run a fresh console internet connectivity check routine.
