Validation Failed Error - Cannot Install ownCloud Appliance in VMware ESXi


I hope you are well. I am trying to install the ownCloud appliance from the App Store ( on its own VM in our hypervisor. It boots up fine but when I about half way through the configuration, up to the page where I input the hostname of the server and root password, after I click Next, it stops at a page stating “Validation failed” and “The following entires could not be validated:” with a big exclamation symbol in a red circle and nothing else; I cannot proceed from there. Is there a bug in the appliance installer?
