Quick Answer
An ERR_CONNECTION_RESET error occurs when the connection between your browser and the website is forcefully closed. To fix it, restart your router and computer, clear browser cache, reset TCP/IP stack, disable VPN and proxy settings, and temporarily disable antivirus. If the error persists, flush DNS cache, reset Chrome settings, or check the hosts file. For more networking troubleshooting, visit our Windows 11 Troubleshooting Hub.

Why ERR_CONNECTION_RESET Happens

An ERR_CONNECTION_RESET error indicates that the connection between your browser and the website was forcefully closed by the server, router, or a firewall. This error is specific to Google Chrome and other Chromium-based browsers, and it occurs when the data packet exchange is interrupted. For official documentation, refer to the Google Chrome net-error-codes documentation.

The ERR_CONNECTION_RESET error is similar to other Chrome errors like Chrome ERR_CONNECTION_TIMED_OUT and Your Connection is Not Private, but it specifically indicates a reset rather than a timeout or certificate issue. Common triggers include antivirus and firewall interference, VPN or proxy misconfiguration, corrupted browser cache, and TCP/IP stack corruption.

Before diving into fixes, ensure you have administrator privileges on your PC. 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_CONNECTION_RESET error can be caused by malware or network monitoring tools. If the error persists, run a malware scan.

1. Restart Your Router and Computer

The simplest fix for an ERR_CONNECTION_RESET 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_CONNECTION_RESET immediately. If not, proceed to the next method.

2. Clear Browser Cache and Cookies

Corrupted browser cache can trigger the ERR_CONNECTION_RESET 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.”

3. Reset TCP/IP Stack and Winsock

A corrupted TCP/IP stack can cause the ERR_CONNECTION_RESET 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_CONNECTION_RESET issues.

4. Disable VPN and Proxy Settings

VPNs and proxy servers can interfere with connections and cause the ERR_CONNECTION_RESET 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 connection resets on certain networks.

5. Temporarily Disable Antivirus and Firewall

Antivirus and firewall software can mistakenly block connections and cause the ERR_CONNECTION_RESET error. Temporarily disabling them can help identify the cause.

  1. Open your antivirus application.
  2. Turn off real-time protection or pause protection temporarily.
  3. Disable the Windows Firewall or any third-party firewall.
  4. Test the website in Chrome.
  5. If the error resolves, add Chrome or the specific website to the exclusion list.
  6. Re-enable your security software immediately after testing.

🔁 Alternative Solution: If you cannot disable your antivirus, try adding Chrome to the exclusion list.

6. Flush DNS Cache

Stale DNS cache entries can cause the ERR_CONNECTION_RESET 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_CONNECTION_RESET 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_CONNECTION_RESET caused by corrupted extensions or settings.

8. Check the Hosts File

Incorrect entries in the hosts file can block domain resolution and cause the ERR_CONNECTION_RESET error.

  1. Navigate to C:\Windows\System32\drivers\etc.
  2. Open the hosts file with Notepad (as administrator).
  3. Look for entries that may be blocking domains (e.g., entries with 127.0.0.1 or 0.0.0.0 followed by a domain name).
  4. If you find suspicious entries, remove or comment them out with a #.
  5. Save the file and restart your PC.

⚠️ Warning: Do not delete the default entries in the hosts file. Only remove custom entries that may be causing issues.

9. Advanced Troubleshooting

If the error persists, try these advanced solutions.

Check for Malware

Malware can cause connection resets. 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.

Update Network Drivers

Outdated network drivers can cause the ERR_CONNECTION_RESET error. Update them via Device Manager or from your manufacturer’s website. For more, see How to Update Drivers Windows 11.

Use the Windows Network Troubleshooter

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

Disable Chrome Extensions

Some extensions can interfere with connections. Go to chrome://extensions and disable all extensions, then re-enable them one by one to find the culprit.
