Seems to work.  I end up in a buffer named " *http jigsaw.w3.org:443*-264606"
(the minus seems weird, perhaps an unrelated misfeature), whose
contents is the entire response from the server, starting with

  HTTP/1.1 200 OK
  date: Tue, 24 Sep 2019 07:11:23 GMT
  content-length: 458
  content-location: https://jigsaw.w3.org/HTTP/Basic/ok.html
  content-type: text/html
  etag: "1lkdfte:qoguo8q8"
  last-modified: Sun, 25 Jun 2000 17:08:58 GMT
  server: Jigsaw/2.3.0-beta3

and ending with this:

  <P>
  <HR>
  <P>Your browser made it!
    </body>
  </html>

Is this what you see?
