Fix ERR_NETWORK_CHANGED in Chrome

What it means

ERR_NETWORK_CHANGED appears when Chrome notices that your network connection changed in the middle of loading a page.

Common causes:

1. A weak Wi-Fi signal, or a problem with the router or the internet provider.
2. Old network drivers.
3. A VPN, firewall or antivirus that interferes.
4. A damaged Chrome cache.
5. Wrong proxy settings.
6. A buggy Chrome extension.

Fixes

1. Basic checks

Reload the page. Restart your router and your computer. Move closer to the router, or use a cable.

2. Flush the DNS cache

On Windows, open Command Prompt as administrator:

ipconfig /flushdns

On macOS:

sudo dscacheutil -flushcache

On Linux, use sudo resolvectl flush-caches.

Also release and renew the IP address on Windows:

ipconfig /release
ipconfig /renew

3. Turn off conflicting software

Turn off the VPN, proxy, firewall or antivirus for a moment and check the page again.

4. Clean up Chrome

Press Ctrl + Shift + Delete. Choose Cookies and other site data and Cached images and files, then click Clear data.

5. Check extensions

Go to chrome://extensions. Turn off all extensions, then turn them on one by one to find the guilty one.

6. More steps

• Update your network adapter driver.
• Check the proxy settings in Windows (Settings, then Network & Internet, then Proxy) and turn off any proxy you do not need.
• Reset the network with netsh winsock reset (Windows, as administrator) and restart the PC.
• Update or reinstall Chrome.

Quick recap

• The error is about a network that changed during loading.
• Restart the router, flush DNS and turn off VPNs.
• Clear the cache and check the extensions.
