Hub: Windows 11 Troubleshooting Hub

Quick Answer
An ERR_NETWORK_CHANGED error occurs when your network connection changes while a request is in progress. To fix it, restart your router and computer, reconnect to your Wi-Fi network, clear browser cache, reset TCP/IP stack, disable VPN and proxy settings, and flush DNS cache. If the error persists, reset Chrome settings or update network drivers. For more networking troubleshooting, visit our Windows 11 Troubleshooting Hub.

Why ERR_NETWORK_CHANGED Happens

An ERR_NETWORK_CHANGED error indicates that the network connection changed while the browser was attempting to load a page. This error is specific to Google Chrome and other Chromium-based browsers, and it occurs when there is a network transition—such as switching from Wi-Fi to Ethernet, changing Wi-Fi networks, or when your IP address changes. For official documentation, refer to the Google Chrome net-error-codes documentation.

The ERR_NETWORK_CHANGED error is similar to other Chrome errors like ERR_CONNECTION_RESET and ERR_CONNECTION_CLOSED, but it specifically indicates a network transition rather than a reset or closure. Common triggers include switching between Wi-Fi networks, using VPNs or proxies, IP address changes, and unstable network connections.

Before diving into fixes, ensure you have a stable internet connection and are not switching networks frequently. If you are on a corporate network, contact your IT administrator before making changes. For a broader overview of network errors, see our Windows 11 Troubleshooting Hub.

⚠️ Warning: An ERR_NETWORK_CHANGED error can occur if you have unstable network connections. Check your network stability before proceeding with advanced fixes.

1. Restart Your Router and Computer

The simplest fix for an ERR_NETWORK_CHANGED error is restarting your router and computer. This clears temporary network glitches and refreshes your IP configuration.

  1. Restart your computer.
  2. Power off your modem and router. Unplug them from power.
  3. Wait 30 seconds, then plug them back in.
  4. Wait for all lights to stabilize, then restart your PC.
  5. Open Chrome and try loading the website again.

✅ Expected Result: A restart often resolves the ERR_NETWORK_CHANGED immediately. If not, proceed to the next method.

2. Reconnect to Your Wi-Fi Network

If the ERR_NETWORK_CHANGED error occurs after switching networks, reconnecting to your Wi-Fi can resolve the issue.

  1. Open Settings > Network & Internet > Wi-Fi.
  2. Click “Disconnect” from your current network.
  3. Wait a few seconds, then click “Connect” to reconnect.
  4. Alternatively, forget the network and reconnect:
    1. Click “Manage known networks”.
    2. Select your network and click “Forget”.
    3. Reconnect by entering the password.
  5. Open Chrome and try loading the website again.

💡 Quick Tip: If you are switching between Wi-Fi and Ethernet, disable Wi-Fi while using Ethernet to avoid conflicts.

3. Clear Browser Cache and Cookies

Corrupted browser cache can trigger the ERR_NETWORK_CHANGED error. Clearing the cache and cookies can resolve it.

  1. Open Chrome and press Ctrl + Shift + Delete.
  2. Select “All time” for time range.
  3. Check “Cookies and other site data” and “Cached images and files”.
  4. Click Clear data.
  5. Restart Chrome and try loading the website again.

💡 Quick Tip: You can also clear Chrome’s internal DNS cache by visiting chrome://net-internals/#dns and clicking “Clear host cache.”

4. Reset TCP/IP Stack and Winsock

A corrupted TCP/IP stack can cause the ERR_NETWORK_CHANGED error. Resetting it restores default network settings.

  1. Open Command Prompt as Administrator.
  2. Run the following commands in sequence:
    netsh int ip reset
netsh winsock reset
  3. Restart your PC.
  4. Try loading the website again.

✅ Expected Result: Resetting the TCP/IP stack often resolves persistent ERR_NETWORK_CHANGED issues.

5. Disable VPN and Proxy Settings

VPNs and proxy servers can interfere with network connections and cause the ERR_NETWORK_CHANGED error. Disabling them can resolve the issue.

  1. Disconnect your VPN if active.
  2. Open Settings > Network & Internet > Proxy.
  3. Ensure “Use a proxy server” is turned Off.
  4. In Chrome, go to chrome://settings/system and ensure “Open your computer’s proxy settings” is not enabled.

❌ Common Mistake: Forgetting to disconnect VPN before testing. VPNs can cause network changes and trigger the ERR_NETWORK_CHANGED error.

6. Flush DNS Cache

Stale DNS cache entries can cause the ERR_NETWORK_CHANGED error. Flushing the DNS cache forces your system to retrieve fresh DNS records.

  1. Open Command Prompt as Administrator.
  2. Run the following command:
    ipconfig /flushdns
  3. Wait for the confirmation message.
  4. Restart your browser and try loading the website again.

💡 Quick Tip: You can also clear Chrome’s internal DNS cache by typing chrome://net-internals/#dns in the address bar and clicking “Clear host cache.”

7. Reset Google Chrome Settings

If the ERR_NETWORK_CHANGED error persists, resetting Chrome to default settings can resolve the issue.

  1. Open Chrome and go to chrome://settings/reset.
  2. Click “Restore settings to their original defaults”.
  3. Click “Reset settings” to confirm.
  4. Restart Chrome and test.

✅ Expected Result: Resetting Chrome often resolves ERR_NETWORK_CHANGED caused by corrupted extensions or settings.

8. Update Network Drivers

Outdated network drivers can cause the ERR_NETWORK_CHANGED error. Updating them can improve network stability.

  1. Open Device Manager.
  2. Expand Network adapters.
  3. Right-click your network adapter and select Update driver.
  4. Select “Search automatically for drivers”.
  5. If Windows doesn’t find updates, visit your manufacturer’s website to download the latest driver.
  6. Restart your PC.

🔁 Alternative Solution: For more detailed driver update guidance, see How to Update Drivers Windows 11.

9. Advanced Troubleshooting

If the error persists, try these advanced solutions.

Check for Malware

Malware can cause network issues. Run a full scan with Windows Defender Offline. For detailed steps, see How to Scan Malware Windows 11.

Disable IPv6

IPv6 can sometimes cause connection issues. Open Control Panel > Network and Sharing Center > Change adapter settings, right-click your connection, select Properties, uncheck Internet Protocol Version 6 (TCP/IPv6), and restart.

Use the Windows Network Troubleshooter

Run the built-in network troubleshooter: Settings > System > Troubleshoot > Other troubleshooters > Internet Connections > Run.

Check for Network Conflicts

If you are using multiple network adapters (Wi-Fi and Ethernet), disable one to avoid conflicts. This can prevent the ERR_NETWORK_CHANGED error.

Perform a System Restore

If the error started after a system change, use System Restore to revert. See How to Use System Restore Windows 11.
