I was trying to migrate Smartermail to an AWS EC2 server, so I can retire my old physical rack-mounted server once and for all.  This seems possible based on documentation, but I hit a snag at the activation step, where it fails and says to contact the sales department.  Self diagnostic yields the following ominous results:

I have an older version, 11.x, but it works fine for my very modest needs.  It activated easily and always worked well on my physical server.  I read a note in documentation about how older versions can't activate lately because they don't support TLS 1.2, but wasn't sure if that was the problem since http (non-encrypted) connection to the activation page also fails.  If that was the problem, is there a work-around?

I also checked the obvious stuff:  FIPS is disabled.  Windows firewall has default settings allowing outbound connections not explicitly forbidden.  AWS has its own sort of firewall utility by the name of "security groups", and all the security groups on my server have a default outbound rule allowing all traffic, all protocols, from all ports to anywhere, so that wouldn't seem to be the problem.  And smartermail seems to be able to connect to yahoo and google OK.

I would appreciate any advice on how to troubleshoot or what to try next.
