I too am now one of the users where my previous working HTTPS links have stopped functioning.
I had the issue several months ago with HTTP links and I changed them over to HTTPS links and they worked until yesterday. Then the links didn't work, and I don't know if it was a "quirk" in the web site or in Excel.
I would appreciate any help in getting the hyperlinks to function again. I would also like to know how to petition Microsoft to support all HTTPS protocol sites.

The moderator, who tried to get the essence of the question, supplied the title of the new question. The asker of the question may change
the title by editing the question, and the moderator will not be offended in any way.
Note from moderator: new questions get answered much faster when asked as new questions. When a new question or follow-up question is tacked
onto an answered question you can only hope a moderator stumbles across it and splits it off, which can take days, or may ever happen.]
