ERR_CONNECTION_RESET means the connection between your browser and the website was interrupted before the page finished loading. The cause can be your network, a VPN, security software, browser settings, or the website itself.
Does this affect you?
Use this for Chrome, Microsoft Edge, and other Chromium browsers on Windows or Mac when a page says the connection was reset or shows ERR_CONNECTION_RESET.
Rule out simple causes
Check the connection before changing deeper settings.
- Force a clean reload with Ctrl+Shift+R on Windows or Cmd+Shift+R on Mac.
- Try a different website. If every site fails, focus on your connection.
- Restart the router by unplugging it for one full minute, then plugging it back in.
- Try another network, wired connection, or phone hotspot.
- If the site fails only on a work or school network, it may be blocked there.
Temporarily test antivirus and VPN
Traffic-scanning tools commonly cause reset errors.
- Open your antivirus settings.
- Look for Web Protection, HTTPS Scanning, SSL Inspection, or similar.
- Turn that feature off briefly for testing.
- Disconnect any VPN.
- Reload the site.
- Turn protection back on after testing and add a proper exception if needed.
Reset network and browser settings
Use this when many sites fail and the connection itself works.
- On Windows, open Command Prompt as administrator.
- Run netsh winsock reset.
- Run netsh int ip reset.
- Restart the computer.
- Check Windows or macOS proxy settings and disable unexpected proxy use.
- In Chrome, reset browser settings from chrome://settings/reset.
More control
Check whether the site is down
If other websites load, the destination site may be overloaded or misconfigured. Try again later or check a site-status service.
Disable extensions one at a time
Ad blockers and privacy extensions can reset connections if they misidentify a page element. Test from chrome://extensions or edge://extensions.
Check firewall blocks
A firewall can reset outgoing connections. Review Windows Security firewall settings or third-party firewall logs for blocked browser traffic.
