Domain Mapping Not Working as Expected

I have the latest version of Domain Mapping installed in a Multi Site network with a VPS - dedicated IP: 198.1.94.27

wp-config
/* Multisite */
define('WP_ALLOW_MULTISITE', true);

define('MULTISITE', true);
define('SUBDOMAIN_INSTALL', true);
define('DOMAIN_CURRENT_SITE', 'www.joviehost.com');
define('PATH_CURRENT_SITE', '/');
define('SITE_ID_CURRENT_SITE', 1);
define('BLOG_ID_CURRENT_SITE', 1);
define( 'DOMAINMAPPING_ALLOWMULTI', 1 );

define('SUNRISE', 'on');

I want to map http://ashlynnhataway.joviehost.com/ to ashlynnhataway.com.

ashlynnhataway.com is registered at Godaddy. I set up the A Record with the above IP address.

Can't get it to work.
