Windows Admin Center Changes Port and Certificate Settings when Server is Rebooted

Hey all,

I am trying to deploy Windows Admin Center. I chose to configure Port 443 and an existing certificate during the install wizard process. However, when the VM in Azure is rebooted, the configs revert to Port 6516 and the certificate that Azure pushes to the VM for WAC. Any ideas on how to keep the changes even when the VM is rebooted?

I've tried going back to the installer to change the Port and Certificate post reboot, and it works until the VM is rebooted again.

When changes are reverted and I try to access https://<fqdn>:6516, I am prompted with a message stating that "Attackers might be trying to steal your information from <fqdn>"

Thank you, in advance!!
