HA configuration for TLS on SBC

I have the TLS configuration working on my primary SBC in an HA pair.  The HA box does not connect though.  Do I have to generate another certificate and get it signed for the second box?  Into another certificate record?  Here is what I have:  The alternative name is the name of the secondary in the HA pair.
