It looks like the git version of the code tickled a bug in python's
libraries.  The clients now fail with:
./cado-nfs-client.py:724: DeprecationWarning: cafile, capath and
cadefault are deprecated, use a custom context instead.  return
urllib_request.urlopen(request, cafile=cafile)

and then 404 with no work found.  This even happens with the normal
invocation of the script.

OS: Fedora 31

Specific libraries and package versions available as requested.
