BitDefender updates resulted in this message being printed:

“we could not verify the certificate: reason = wrongHost”

“we could not verify the certificate: reason = untrusted”

And on further inspection, it is revealed the BitDefender is indeed the culprit via it’s Parental Controls:

To fix this, I uninstalled BitDefender Parental Control in Windows, as it didn’t have any apparent configuration to refine the blockage of the internal DNS site.  Reinstalled just BitDefender Total Security to address the problem, all the while trying not to install BitDefender Parental Control.  Hope this helps!
