If your domain is pointing to the CloudSites nameservers all you have to do is put your domain in a browser. CloudSites Nameservers
if your domain is not pointing to gearhost yet you can use a preview URL.
Note: Replace FQDN with your own domain.
A link to the preview URL for your domain can be found under the "Details" tab of the domain manager section in the myCloud control panel. If the site comes up when using the preview URL then you know that everything has been setup correctly!
Note: The preview page will not function correctly for subdomains of your site as the preview page makes your domain a subdomain of gearhost. To view subdomains add the folder path at the end of the preview page.
