Resolved In Version:

Problem is fixed in version: PAC Firmware R9.4c


Symptoms:

When a SNAP PAC controller tries to connect to a secure server (with SSL or TLS encryption), if the secure server has a certificate name that differs from the DNS name required to connect to the server, then you may get a -2104 error.
 
Note: A more common cause of a -2104 error is a missing or incorrect certificate, so check to make sure the correct certificate is installed on the SNAP PAC controller.

The following PAC Control commands could be affected:

  • HTTP Get
  • HTTP Post From String Table
  • Send Email
  • Send Email With Attachments
