SMTP error 10060 signifies that your email server failed to establish a connection with the recipient's server within the designated timeframe (phpmailer, jenkins). This indicates a communication breakdown during the email sending process.
What Triggers This Error?
Several factors can contribute to this error:
- Incorrect Server Details: Invalid SMTP host address, port number, or authentication credentials (phpmailer, jenkins).
- Network Connectivity Issues: Network problems on the sending server preventing it from reaching the recipient's server.
- Firewall Blocking: Firewalls or security measures on either server might be blocking communication.
Resolving SMTP Connect Error 10060
Here's how to troubleshoot and fix this error:
- Verify Server Configuration: Double-check the SMTP host address, port number, and authentication details (username and password) for accuracy (phpmailer, jenkins).
- Test Network Connectivity: Use tools like ping or telnet to verify network connectivity between the sending server and the recipient's server.
- Review Firewall Settings: Ensure firewalls on both servers allow communication on the required ports used for SMTP (typically port 25 or 587).
- Check Authentication: If using SMTP authentication, confirm the credentials are valid and have the necessary permissions.
By addressing these potential causes, you can establish a successful connection between the servers and ensure smooth email delivery.
