How to fix the error ERR_CONNECTION_RESET

The error ERR_CONNECTION_RESET typically occurs when the connection between your device and the server is interrupted. It might be due to network issues, browser settings, or server configurations. Often just retrying the page may help. If the error persists, here are some steps to troubleshoot and resolve this error:

1. Check Your Internet Connection

• Ensure your device is connected to the internet.
• Restart your router or modem.
• Try connecting to another network to see if the problem persists.

2. Disable Proxy Settings

• Windows:
  • Go to Control Panel > Internet Options > Connections > LAN settings.
  • Uncheck Use a proxy server for your LAN and check Automatically detect settings.
  • Click OK to save changes.
• Mac:
  • Go to System Preferences > Network.
  • Select your network, click Advanced, and go to the Proxies tab.
  • Ensure no proxies are selected.

3. Disable VPN or Firewall

• If you’re using a VPN, disconnect it and try again.
• Temporarily disable your firewall or antivirus software to see if it’s blocking the connection. If the error resolves, whitelist the website or application causing the issue.

4. Clear Browser Data

• Open your browser and clear cookies, cache, and browsing data:
  • Chrome: Menu > More tools > Clear browsing data.
  • Select Cookies and other site data and Cached images and files.
  • Click Clear data.

5. Reset Network Settings

• Windows:
  • Open Command Prompt as an Administrator.
  • Run the following commands:
    cmd

    Copy code

    netsh int ip reset
netsh winsock reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns

  • Restart your computer.
• Mac:
  • Open Terminal and run:
    bash

    Copy code

    sudo dscacheutil -flushcache
sudo killall -HUP mDNSResponder


6. Check MTU Settings

If you’re on a specific network, an incorrect MTU (Maximum Transmission Unit) setting might cause issues:

• Open Command Prompt and run:
  cmd

  Copy code

  ping google.com -f -l 1472

  • If it shows “Packet needs to be fragmented,” reduce the value by 10 and try again until it succeeds.
  • Update the MTU in your router or device settings accordingly.

7. Test with Another Browser or Device

• Try accessing the website using a different browser or device.
• If it works, the issue might be browser-specific, and you may need to update or reset your browser.

8. Check Server-Side Issues

• If the problem occurs only with a specific website, it might be down or facing issues.
• Check the website on DownForEveryoneOrJustMe to confirm.

9. Reinstall/Update Network Drivers

• Ensure your network adapter drivers are up to date. If not:
  • Open Device Manager, find your network adapter, right-click, and select Update driver.
  • Alternatively, uninstall and reinstall the driver.
