How to Fix ERR_CONNECTION_REFUSED Error

The ERR_CONNECTION_REFUSED error appears when your browser cannot establish a connection to a website's server. This error indicates the server actively rejected your connection request, typically due to network configuration issues, firewall blocks, or server problems.

  1. Check your internet connection. Open a new browser tab and navigate to a different website like google.com or apple.com. If other sites load normally, the issue is specific to the original website. If no sites load, restart your router by unplugging it for 30 seconds, then plugging it back in.
  2. Clear browser cache and cookies. Press Ctrl+Shift+Delete (Windows) or Cmd+Shift+Delete (Mac) to open the clear browsing data dialog. Select 'All time' as the time range and check 'Cookies and other site data' and 'Cached images and files'. Click 'Clear data' and restart your browser.
  3. Disable browser extensions. Type chrome://extensions/ in Chrome's address bar or about:addons in Firefox. Disable all extensions by toggling them off. Refresh the problematic website to see if an extension was blocking the connection. If the site loads, re-enable extensions one by one to identify the culprit.
  4. Flush DNS cache. Open Command Prompt as administrator (Windows) or Terminal (Mac). On Windows, type 'ipconfig /flushdns' and press Enter. On Mac, type 'sudo dscacheutil -flushcache' and press Enter. Restart your browser and try accessing the website again.
  5. Check firewall and antivirus settings. Temporarily disable Windows Defender Firewall or your third-party firewall software. Try accessing the website again. If it loads, add your browser to the firewall's exception list. Re-enable the firewall immediately after testing.
  6. Try a different DNS server. Open Network Settings and change your DNS servers to Google's public DNS: 8.8.8.8 and 8.8.4.4, or Cloudflare's: 1.1.1.1 and 1.0.0.1. On Windows, go to Network & Internet > Change adapter options > right-click your connection > Properties > Internet Protocol Version 4 > Properties. Enter the new DNS addresses and click OK.
  7. Reset network settings. Open Command Prompt as administrator and run these commands in order: 'netsh winsock reset', 'netsh int ip reset', and 'ipconfig /release' followed by 'ipconfig /renew'. Restart your computer after running all commands.
