Resolution

It is recommended that the key have a SAN that uses the IP, server name, and fully qualified domain name (FQDN).  If the certificate is one in particular, use just that one.  If it has two of these three, try each one.  The problem is that the AE is picking up one of them, but the agent is using the other.
