Focus your efforts on understanding the specific error code. The “Serp,5185.1” error often points to a problem with your server’s SSL certificate configuration. Check your certificate’s expiration date immediately; a lapsed certificate is the most common culprit.
Next, verify the certificate’s chain of trust. Ensure all intermediate certificates are correctly installed and that the root certificate authority is recognized by your server. Incorrectly configured certificate chains frequently cause this type of error. Use a certificate validation tool to check this quickly.
If the certificate and chain are valid, investigate your server’s configuration files. Mismatched port settings or incorrect virtual host configurations can lead to this error. Double-check Apache or Nginx settings for typos or inconsistencies. Restart your server after making any changes.
Finally, consider your server’s operating system. Outdated or improperly configured operating system settings might interfere with SSL/TLS handshake. Apply all available security updates and review relevant documentation. Remember to back up your configuration files before making any significant adjustments.
