If you are trying to view a recently created domain (or if you have recently changed the IP address to a website / domain name) and are encountering cPanels "Default Webpage", the likely culprit is DNS Propagation issues, as the changes have not reflected globally.
You can use one of the many online DNS checking websites, https://www.whatsmydns.net/ which can assist in confirming this is the case, as a multitude of different options can be selected depending on your requirements.
Should your domain reside on our Servers Australia DNS Cluster, please don't hesitate to reach out to our Support Team. A Support Case can be lodged via the MySAU portal or alternatively call us on 1300 768 862.
