CURLECONNECTIONREFUSED

CURLECONNECTIONREFUSED is an error message that typically indicates a problem with establishing a network connection. It most commonly occurs when using the cURL command-line tool or libraries that rely on cURL for network operations. The error signifies that the remote server or host actively rejected the connection attempt. This rejection is not due to a timeout, but rather an explicit refusal from the server's end.

Several factors can lead to this error. A common cause is that the server is not running or is not listening on the specified port. Another possibility is that a firewall on either the client or server side is blocking the connection. Incorrect server address or port number in the cURL command can also result in this error. Network configuration issues, such as DNS resolution problems or routing errors, might also contribute.

To troubleshoot CURLECONNECTIONREFUSED, verify that the server is operational and accessible. Check that the correct IP address or hostname and port number are being used. Examine firewall rules to ensure no restrictions are in place. Confirm that DNS resolution is functioning correctly for the target host. If the issue persists, further investigation into the server's network services and logs may be necessary.
