When trying to download GDAX data with the ToolBox, I get the error:

20200522 18:08:03.270 ERROR:: GDAXDownloaderProgram.GDAXDownloader(): System.Net.WebException: The request was aborted: Could not create SSL/TLS secure channel.

Initial searches tell me this is related to the TLS protocol used, but I was hoping someone else had some insight before I dug in any deeper.
