How to fix error error-connection-refused in Windows 11

Solution Steps

1. 1 First, verify that the server is actually down by trying to access it from another device (like your phone). If it works on your phone, the issue is on your PC.
2. 2 Press Windows key + R, type 'firewall.cpl', and press Enter. Click 'Allow an app or feature through Windows Defender Firewall'. Ensure the app you're trying to use is allowed. If not, click 'Change settings' and add it.
3. 3 If you're using a third-party firewall, temporarily disable it to see if it's blocking the connection. If it is, add an exception for the app.
4. 4 Open Command Prompt as admin and run 'netstat -an' to see if the port you're trying to connect to is listening. If the port is not listening, the server might be down.
5. 5 Try flushing DNS with 'ipconfig /flushdns' and resetting Winsock with 'netsh winsock reset'.
