Thank you for the reply. That certainly helped. The keys now show up in the directory where they should have showed before (although for some reason I don't recall doing the steps you outlined as part of the how-to)...
Now, whether I use https://my_ip_address:81
or http , I get
"The connection was refused when attempting to contact my_ip_address:81"
the box is alive, and it can be ping-ed...
the logs don't have any strange entries in them, so according to the installation and setup, everything "looks" as though it went fine.
I appreciate your feedback.
