📋

Preliminary Fast Checks

Verify these 3 simple prerequisites before proceeding to in-depth fixes:

Check 'Proxy Settings' in Windows to ensure 'Use a proxy server' is toggled OFF. Restart your web browser with all extensions disabled. Test another browser (like Edge or Firefox) to see if the refusal is system-wide.

DEEP DIVE

🔬 Root Cause: Why Does ERR_CONNECTION_REFUSED Occur?

ERR_CONNECTION_REFUSED means the target server or local port actively sent a TCP RST (reset) packet back to your browser, indicating that no listening socket is accepting connections on that port, or a local proxy server is misconfigured.

🔍 Primary Triggers for ERR_CONNECTION_REFUSED

The destination web server is down or its web service (Nginx/Apache) has stopped.
An unauthorized proxy server has been enabled in Windows Internet Settings.
Third-party antivirus or firewall blocking browser ports.
Corrupted browser cookies and cached network sockets.

⚠️ CRITICAL WARNING

What NOT to Do

Do not disable Windows Defender Firewall permanently; add a browser rule instead.

Complete Step-by-Step Solutions for ERR_CONNECTION_REFUSED

Execute these verified methods sequentially from easiest to most advanced:

Disable Proxy Server in Windows Settings

Malware or VPN uninstallations often leave ghost proxy settings active.

Command Prompt / PowerShell (Admin)

ms-settings:network-proxy

Press Win + R, paste the command above, press Enter. Ensure 'Automatically detect settings' is ON, and 'Use a proxy server' is toggled OFF.

Clear Chrome Browser Cache & Sockets

Force Chrome to re-negotiate fresh TCP connection handshakes.

In Chrome, paste 'chrome://net-internals/#sockets' in the URL bar, and click 'Flush socket pools'. Next, press Ctrl + Shift + Del and clear cache.

Reset Network Stack via Command Prompt

Rebuild Windows Winsock catalog and IP routing.

Command Prompt / PowerShell (Admin)

netsh winsock reset

Run Command Prompt as Administrator, execute the command above, then run 'netsh int ip reset', and restart your PC.

It can be both. If other sites work, the specific website server may be offline. If NO websites work, the issue is on your PC or proxy.

If developing local apps (Node.js, Python, XAMPP), it means your local server process isn't running or isn't listening on that specific port.
