ERR_NETWORK_CHANGED: How to Fix Chrome Error

This guide walks you through fixing the ERR_NETWORK_CHANGED error in Google Chrome, which typically appears when your internet connection drops or changes while a page is loading. You’ll learn the most effective fixes, from simple refreshes to deeper network resets, so you can get back to browsing quickly.

What You’ll Need

Access to your router or modem (to restart it if needed)
Administrator rights on your computer (for some steps)
Your Wi-Fi password (if you need to reconnect)

Step-by-Step

Refresh the page. The error is often temporary. Press Ctrl+R (Windows) or Cmd+R (Mac), or click the reload icon. If the page loads, you’re done.
Check your internet connection. Open another website or run a quick speed test. If nothing loads, your network is down—move to step 3. If other sites work, the problem is specific to that page or Chrome.
Restart your router and modem. Unplug both devices, wait 30 seconds, plug the modem back in, wait for it to fully boot (lights stabilize), then plug in the router. Once the router is back online, try Chrome again.
Toggle Wi-Fi off and on. Click the network icon in your taskbar (Windows) or menu bar (Mac), turn off Wi-Fi, wait 10 seconds, and turn it back on. Reconnect to your network and try the page again.
Disable and re-enable your network adapter. On Windows: open Control Panel > Network and Sharing Center > Change adapter settings. Right-click your active adapter (Wi-Fi or Ethernet) and select Disable. Wait 10 seconds, then right-click and select Enable. On Mac: go to System Settings > Network, select your connection, and toggle it off and on.
Clear Chrome’s DNS cache. In a new tab, type chrome://net-internals/#dns and press Enter. Click the Clear host cache button. Then go to chrome://net-internals/#sockets and click Flush socket pools. Restart Chrome.
Change your DNS server. If the error persists, your ISP’s DNS may be unstable. Switch to a public DNS like Google (8.8.8.8 and 8.8.4.4) or Cloudflare (1.1.1.1). On Windows: go to Network Settings > Change adapter options, right-click your adapter, select Properties, choose Internet Protocol Version 4 (TCP/IPv4), and enter the DNS addresses. On Mac: System Settings > Network > your connection > Details > DNS.
Disable VPN or proxy extensions. VPNs and proxy extensions can cause network changes. Temporarily disable them: click the puzzle icon in Chrome’s toolbar, find your VPN/proxy extension, and select Remove from Chrome or toggle it off. Try the page again.
Reset Chrome’s network settings. In Chrome, go to Settings > Privacy and security > Security. Scroll down and click Reset next to “Reset network settings”. Confirm and restart Chrome.
Run a network reset (Windows only). Open Command Prompt as administrator (search “cmd”, right-click, “Run as administrator”). Type the following commands one by one, pressing Enter after each:

ipconfig /release

ipconfig /renew

ipconfig /flushdns

netsh winsock reset

netsh int ip reset

Restart your computer.

Common Mistakes

Skipping the router restart. A quick refresh often works, but if the error repeats, a full router cycle is the most reliable fix.
Not checking for VPN interference. Many people forget that a VPN can cause this error, especially if it switches servers automatically.
Only clearing the browser cache. The DNS cache is separate and more likely to be the culprit.
Disabling the wrong network adapter. If you have both Wi-Fi and Ethernet, disable the one you’re not using to avoid confusion.

Tips

Use a wired connection temporarily. If you’re on Wi-Fi, plugging in an Ethernet cable can stabilize the connection and help isolate the issue.
Update your network drivers. Outdated drivers can cause intermittent drops. On Windows, go to Device Manager > Network adapters, right-click your adapter, and select Update driver.
Check for router firmware updates. Log into your router’s admin page (usually 192.168.1.1 or 192.168.0.1) and look for a firmware update option.
Disable Wi-Fi power saving. On some laptops, Wi-Fi power saving can cause the adapter to sleep. In Device Manager, right-click your Wi-Fi adapter, go to Power Management, and uncheck “Allow the computer to turn off this device to save power.”

Troubleshooting

If the error still appears after trying all the steps above, consider the following:

Try a different browser. If the error only happens in Chrome, the issue is browser-specific. If it happens in Firefox or Edge too, it’s your network.
Check for malware. Some malware can interfere with network settings. Run a full system scan with Windows Defender or your preferred antivirus.
Contact your ISP. If the error occurs on all devices and at different times, your internet service may be unstable. Call your provider and describe the issue.
Reset Chrome completely. Go to Settings > Advanced > Reset and clean up > Restore settings to their original defaults. This will disable extensions and clear temporary data, but your bookmarks and passwords will be kept.

Frequently Asked Questions

Why does ERR_NETWORK_CHANGED keep happening?

It usually means your IP address or network connection changed while Chrome was loading a page. This can be caused by Wi-Fi signal drops, VPN toggling, router reconnects, or ISP hiccups.

Does this error mean my internet is down?

Not necessarily. It often happens when the connection briefly drops and then reconnects, or when you switch between networks (e.g., from Wi-Fi to mobile hotspot). The page you were loading may just need a refresh.

Will clearing my browser history fix it?

Clearing your cache and cookies can help if the error is related to corrupted cached data, but it’s not the first thing to try. Start with a simple refresh and router restart.

Can a VPN cause this error?

Yes, VPNs frequently cause this error because they change your network route. If you’re using a VPN, try disconnecting it or switching to a different server.

Is this error dangerous?

No, it’s a harmless network error. It doesn’t indicate a security threat or data loss. It just means the connection was interrupted.

How do I fix this on my phone?

On mobile, toggle airplane mode on and off, then try again. You can also forget the Wi-Fi network and reconnect, or restart your phone.
