You finally sit down after a long day, boot up your console, and get slapped with a frustrating message: “Could not connect to the server,” followed by PlayStation Error WS-37397-9.
Before you panic, take a deep breath. Despite how it looks, your PlayStation account is almost certainly not banned.
This error usually indicates that your PlayStation console cannot establish a connection with the PlayStation Network. Depending on the situation, the cause could be a PlayStation Network outage, an ISP routing problem, a temporary authentication issue, or a temporary restriction affecting your public IP address. Whether you are caught in a widespread server crash or dealing with a temporary routing block, we have you covered. Here is a complete breakdown of why your network might be rejected and the practical troubleshooting steps to get your console back online right now.
What Causes PlayStation Error WS-37397-9: PSN Outages, IP Bans, and Routing Issues
Before diving into complex fixes, it is helpful to understand what actually triggers this connection failure. The error simply means your console cannot reach Sony’s servers, which can occur for several distinct reasons:
- PlayStation Network Outage or Maintenance: Sometimes the servers crash, or Sony takes them offline for scheduled maintenance. When this happens, all incoming connections are rejected.
- Public IP Restrictions: If PSN is operating normally, Sony states that your public IP address may have been blocked due to suspicious activity or Terms of Service violations.
- Temporary PSN Authentication Problems: Glitches in Sony’s login systems can occasionally throw this error when you try to sign in.
- Shared Public IP (CGNAT): Some Internet Service Providers bundle multiple households under a single public IP address. If someone else sharing your IP violates Sony’s rules, the entire address might be temporarily restricted.
- ISP Routing Problems: Your internet provider might be experiencing routing issues that prevent traffic from securely reaching PlayStation servers.
- VPN or Proxy Interference: Using a Virtual Private Network or proxy at the router level can disrupt PlayStation’s strict authentication protocols.
- Malware on Connected Devices: A virus on a PC or smartphone connected to your home network could be sending spam traffic, triggering an automated network-level block.
- DNS Resolution Problems: Occasionally, your ISP’s default Domain Name System (DNS) fails to resolve the PlayStation server addresses properly.
Quick Diagnostic Guide for PSN Error WS-37397-9
| Possible Cause | What to Do First |
| PlayStation Network outage | Check PSN Status |

What Does the WS-37397-9 Error Message Actually Mean for Your PSN Account?
According to Sony’s official documentation, if there are no widespread server outages, error WS-37397-9 can occur when your public IP address has been temporarily blocked from accessing the PlayStation Network.
Sony uses automated security systems to protect PSN from DDoS attacks, malicious traffic, and server abuse. If their systems detect suspicious activity originating from your router’s IP address, Sony may temporarily restrict access from that public IP address to protect the network.
Tip: Want to know if your account is safe? Turn off your smartphone’s Wi-Fi and try logging into the PlayStation App using cellular data. If it works perfectly, your account is fine—the issue strongly suggests a problem related to your home network, ISP routing, or the public IP assigned to your connection!
The Shared IP (CGNAT) Scenario: How Your ISP Affects PlayStation Network Access
If you are a regular gamer who hasn’t done anything wrong, you might be wondering why your IP would be targeted. One possible explanation involves how your internet is routed.
To save resources, some Internet Service Providers (ISPs) use a system called Carrier-Grade NAT (CGNAT). In simple terms, this means your ISP assigns a shared public IP address to multiple homes. If you happen to share a public IP with another customer whose network is infected with malware or who is abusing the PlayStation servers, Sony’s automated systems might temporarily restrict access from that IP. When this happens, everyone grouped under that address—including you—could temporarily lose access.

| Official PlayStation Guidance | Community Findings |
| Check PSN status first | Mobile hotspot helps identify IP-related issues |
| Scan devices for malware | Restarting the router sometimes results in a new public IP |
| Contact your ISP | Some users regain access after their ISP assigns a different IP |
The Verdict: Official guidance and community experiences strongly support each other. While community findings are not official confirmation, they provide practical, real-world ways to apply Sony’s advice—such as using a mobile hotspot to quickly test if the issue is tied to your home’s IP address.
Common Misconceptions About PS4 Error WS-37397-9 and Account Bans
When looking for answers online, you will likely encounter outdated or incorrect advice. Let’s clear up a few myths right now.
- “My PSN account is permanently banned.” False. This is a network connection failure, not an account ban. Your games, trophies, and wallet funds are safe.
- “I need to factory reset my PS4.” False. Resetting your console deletes your data but does nothing to change how your network routes traffic.
- “Reinstalling the game will fix it.” False. The error happens at the network level before you even load into a game.
How to Fix Error Code WS-37397-9: Step-by-Step PSN Connection Solutions
If you are locked out of your favorite games, follow these troubleshooting steps in order. We have organized them from the easiest verifications to the most advanced network fixes.
Step 1: Check the Real PSN Server Status for Active PlayStation Network Outages
Why this works: If the servers are down, no local network fix will get you online.
- Visit the official PlayStation Network Status page on your phone or PC.
- Check if all services are green and operational.
Expected result: If you see red or yellow warnings, there is an active outage. You simply need to wait for Sony to restore service. If the servers are green, move to the next step.
Step 2: Restart Your PlayStation Console to Clear Network Caches
Why this works: Restarting the console clears temporary authentication sessions, refreshes cached network information, and resolves minor connection glitches.
- Press and hold the PS button on your controller.
- Navigate to Power, then select Restart PS4 (or Restart PS5).
- Wait for the console to fully reboot and attempt to sign in again.
Expected result: If the issue was caused by a temporary authentication or networking glitch, the console should reconnect successfully.
Step 3: Do the Mobile Hotspot Test to Identify Home Wi-Fi or IP Issues
Why this works: This quickly confirms whether the connection problem is isolated to your home Wi-Fi.
- Turn on the mobile hotspot feature on your iOS or Android device.
- Go to your console’s Settings > Network > Set Up Internet Connection.
- Connect your PlayStation to your phone’s hotspot.
Expected result: If your console connects to PSN instantly, it confirms the connection problem is isolated to your home network, ISP routing, or your assigned public IP address.
Step 4: Disable Router VPN or Proxy Connections Blocking PSN Access
Why this works: PlayStation Network has strict security protocols that frequently reject traffic coming from known VPN servers or proxy networks.
- If you have a VPN installed on your home router, log into your router’s admin panel and disable it.
- If you manually entered proxy server settings on your PlayStation, go to Settings > Network > Set Up Internet Connection, choose Custom, and ensure Proxy Server is set to Do Not Use.
Expected result: Disabling these services routes your traffic directly through your ISP, satisfying Sony’s security checks and often clearing the error immediately.
Step 5: Reboot Your Wi-Fi Router to Request a New Public IP Address
Why this works: Many residential internet connections use dynamic public IP addresses. Restarting your modem or router may result in a different public IP address being assigned. Whether this actually happens depends heavily on your ISP’s lease policy—some grant a new IP immediately, while others lock the same IP to your modem for days.
- Unplug both your modem and router from the wall outlet.
- Wait for at least 5 to 10 minutes to allow your connection to fully clear.
- Plug everything back in, wait for the lights to stabilize, and connect your PlayStation.
Expected result: If your ISP assigns you a new IP address, you may be able to connect to the servers without issue.
Step 6: Scan Your Home Network Devices for Malware Triggering Sony’s IP Block
Why this works: This is Sony’s official recommendation. A virus on a connected device could be silently sending bad traffic, triggering the network block.
- Open your trusted security software (like Windows Defender or Malwarebytes).
- Run a full system scan on every PC, laptop, and smart device connected to your Wi-Fi.
- Quarantine or delete any detected threats.
Expected result: Removing the malware stops the suspicious traffic. According to Sony’s official guidance, once the underlying issue is resolved, the IP address assigned to your connection will automatically be unblocked.
Step 7: Contact Your Internet Service Provider (ISP) to Fix Network Routing
Why this works: If your equipment reboot didn’t change your public IP or fix routing issues, your ISP has the tools to investigate and resolve it on their end.
Call your ISP’s technical support and explain that you are unable to reach a specific gaming server. Ask them:
- Can you assign a new public IP address to my modem?
- Are there any known routing issues to PlayStation servers?
- Is my connection using Carrier-Grade NAT (CGNAT)?
Note: Some advanced users opt to purchase a static IP address to avoid sharing IPs with strangers, but this usually incurs a monthly fee and is not strictly necessary for most households.
How to Prevent PlayStation Error WS-37397-9 from Blocking Your Network Again
Nobody wants to deal with network troubleshooting when they just want to play a game. You can minimize the chances of seeing this error again by following a few simple best practices:
- Keep your devices clean: Regularly run malware scans on all laptops and Android devices connected to your Wi-Fi.
- Update your equipment: Ensure your router’s firmware is up to date to prevent network security vulnerabilities.
- Avoid unnecessary routing: Turn off router-level VPNs or proxies while using the PlayStation Network unless necessary.
- Power cycle regularly: Restarting your networking equipment occasionally helps clear temporary routing glitches.
- Use a stable connection: Always use a wired ethernet connection or a stable Wi-Fi setup whenever possible.
Tip: If you frequently experience IP-related errors and suspect your ISP’s CGNAT system is to blame, contact your provider. Some ISPs may offer to move customers off CGNAT or manually assign a different public IP address. Keep in mind that availability depends entirely on your ISP, region, and specific service plan.
Frequently Asked Questions (FAQ) About PSN Error WS-37397-9
Can changing DNS fix WS-37397-9?
Sometimes. If the error is caused by your ISP’s DNS servers failing to locate the PlayStation Network, changing your console’s DNS settings to a public option like Google (8.8.8.8) or Cloudflare (1.1.1.1) can restore your connection.
Why does my PlayStation work on a hotspot but not my home Wi-Fi?
Your mobile carrier assigns a completely different IP address and routing path than your home internet provider. If the hotspot works, it confirms your account is fine and the issue is restricted to your home network’s routing or IP.
Does restarting my router always change my public IP address?
No. While it works for many dynamic IP connections, some ISPs assign long “lease times” to IP addresses, meaning you will get the exact same address back even after a reboot.
Can WS-37397-9 appear during PlayStation Network maintenance?
Yes. When the servers are down for maintenance, they reject all incoming connection attempts, which can frequently trigger this exact error code. Always check the PSN status page first.
Does rebuilding the PS4 database fix WS-37397-9?
Usually, no. Rebuilding the database organizes data on your hard drive to make the system run faster, but it does not change your network settings or IP address.
Is this error temporary?
Yes. According to PlayStation Support, once the underlying network issue or suspicious traffic is resolved, the IP address assigned to your connection will be automatically unblocked.
