Solution:

The page examplesite.com/xmlrpc.php must return the following message:

XML-RPC server accepts POST requests only.

Instead it returned a 404 “Not Found” error for this page.

The page /xmlrpc.php returned a 404 error because WordPress was not installed in the root directory. Moving the installation fixed everything, returning the correct message:

XML-RPC server accepts POST requests only.

Thanks so much for the tips Michelle. The page /xmlrpc.php was inaccessible because WordPress was not installed in the root directory. Moving the installation fixed everything, allowed access.
