HTTPS requires Basic authentication, HTTP uses Digest authentication.
You can try switching to HTTP and see if that works.

Thank you - that worked.

So why are we getting emails from the MLS telling us Paragon made a change, and to use the aforementioned url if said url doesn't work?

`To : Greenville SC MLS Data Services Vendors

If you are experiencing failures when logging into the Greenville SC MLS RETS URL for accessing data feeds:

We determined that our data feed services provider, Black Knight, accidentally removed an element of the older URL in a system maintenance Wednesday night, May 17th, with no notification to the MLS of that change.

I sent out notice of an upcoming change to HTTPS format in early

The HTTPS URL does work and the goal is to deprecate all HTTP access sometime in the future.
Paragon RETS HTTPS requires you to use Basic Authentication as I mentioned above.
Which means you may have to make changes in whatever client or library you are using for RETS access.
Also the server/computer you are running your client on must support TLS 1.2 for HTTPS connections.
