In sorting out things today for the repro, I sorted out the way to do this.
I had to do a modification of the document I referenced.
The part I was overlooking was the bitnami.conf file
Due to the passage of time, I can't even recall what I was doing incorrectly for sure to cause the crash.
But I now have opencart properly responding on 8443 with the self SSL certificate with some post deployment modifications.
Too bad that quick to mark as a solution locks the post.
While I have the site responding on port 8443..
I have one remaining issue: When a link is selected, the port 8443 is lost. The application is rendering HTTP URLs instead of maintaining HTTPS or HTTPS://:8443
But then, this appears to be a general issue, as without the port in the URL I get HTTP links for browsing components as well.
