1. The error indicates that the certificate the server is using is invalid, mainly because it is using a certificate that has a different name(hostname) on it. Therefore, ensure that the SSL certificate used does not have any naming mismatch issues.
2. Make sure that the root/ intermediate certificates are added to the "Trusted Root store"  on the machine running the TIBCO Spotfire Automation ClientJobSender.
3. Make sure that SSL certificate is not revoked.
