This error can be seen as a result of an anti-virus software blocking the SMTP service request that Spotfire Automation Services is using for email. It could also be due to SMTP communication not being allowed on the used port.

Resolution

In this case, check with the IT/Security team to add an exception in the anti-virus scanning rules to allow SMTP request from the TIBCO Spotfire Node Manager machine where TIBCO Spotfire Automation Services is installed.
