The URL was updated in a release near the beginning of the month:

Let me go double-check what the status is of the latest Anaconda build for Skyfield.

The release of 1.45 was delayed for Anaconda by a problem they've been having with Azure producing inaccurate floating point math:

I've told Anaconda to go ahead and build the new version anyway. Hopefully later today you'll be able to ask Anaconda to upgrade Skyfield, and the download will start working again!
