I faced the same issue, but resolved it by editing default TCP/IP stack and add my domain name, then regenerate the SSL thumbprint and populate in the parameter sheet. this makes <yourhostname.yourdomainname>bind with ssl thumprint.

Subject: VCF Buildout: Preparing Security Requirements for Running Validation Skipped
VCF version: VMware Cloud Foundation 5.1.0.0-22688368.
Progress fails at "Preparing Security Requirements for Running Validation" fails with "Skipped" message. Subsequently all other steps failed with "Skipped" message.

I have gathered the SSH RSA Key Fingerprints & SSL Thumbprints with the same procedure as in the older versions. Please assist if there is a different way to capture this data.
