There is /nothing/ /whatsoever / to suggest that this has anything to do with my personal preferences for the location of the various TeX-MF directories, which is the only part of the installation that I modify  Everything else is out of the box.
Here is a simple console session which demonstrates that "wget" can access secure sites only if "--no-check-certificate" is specified, which is not one of the options specified in the TLMGR call thereof :

Is there perhaps a tacit assumption that the users "wgetrc" file will contain "--no-check-certificate" ?

Simple demo of command-line WGET to secure location without and with "--no-check-certificate" —
