This part always confuses me
I supply the trust and key store files on the command line and I see the
SAN for the tomcat server IP (in ObjectId #3). I try to connect to
tomcat by host-IP and port. Here's the text of the keystore sent in.

but I get

Then comes my summary log:

I had this overall configuration working until I 'terminated' the AWS
server instance and am trying to rebuild.
Could a lack of network connectivity between client and server present
this same symptom?
