Domain mapping not working on Siteground hosting

I have been trying out WPEngine and now Siteground. WPEngine never worked with the validation for the DNS on and with Siteground the plugin does not seem to be working at all. When the validation is on it just throws up the error that the domain has not been pointed yet.

In the case of the domain being pointed to the correct IP it has been done and even turning off the validation checks the plugin still does not work. I just get the hosts error message.

Any insight here would be great as I am stuck. I have verified the wpconfig settings, the .htaccess settings, sunrise.php is in the right place. I appreciate the assistance.
