Thanks, NetWallah.

I am assuming that you are suggesting the bottom three addresses in the list you gave. My browser doesn't recognize the top three as URLs.

Each of those bottom three addresses gives the same result: 

  Error 1003 Ray ID: 6651ee569bb639f6 • 2021-06-25 23:21:14 UTC
  Direct IP access not allowed
  What happened?
  You've requested an IP address that is part of the Cloudflare networ
+k.
  A valid Host header must be supplied to reach the desired website.

You said, "Looks like you are connecting via IPV6 - and there may be issues with that." Again, I'm out of my depth here, but is there no way to just say, "Please don't use IPV6" (perhaps just for this site)? And why would IPV6 be a problem? And why would this be happening with just this one particular web site. I do a _lot_ of web reading on a widely varied range of sites -- and this is the only case where this problem has come up.

This article: 

   IPv6 support on Chrome OS

seemed promising until I remembered that this problem is occurring with Chrome, Vivaldi, Edge, _and_ wget on (variously) Chrome OS, Windows, Android, and Debian. Are the suggestions on that page relevant for all access to IPV6 from this side of my router?
