Deploy vcenter 6 with external psc. firstboot script execution error. SSL certificate does not match

Hi
 
I've successfully deploy external PSC. When I continue to deploy the vcenter appliance I got the error firstboot script execution error. The ssl certificate does not match when connecting to the vcenter single sign-on.
 
I refer to this blog for troubleshooting https://techbrainblog.com/2015/10/03/vcsa-6-0-installation-issues-firstboot-script-execution-error/ but when deploying the vcenter the IP of the external PSC i enter was correct. Also i checked the DNS and both PSC and Vcenter name able to resolve correctly. The DNS I'm using is the AD DNS.

Both appliance are deployed on the same esxi host. I'm deploying the appliance through a jumphost.
 
If I were to try and install the vcenter again, could i just power down the failed Vcenter and delete it?

I would try again, confirming the issues reported are correct.

e.g. DNS and FQDN and IP DNS resolution are very important.

Also grab the logs, what do the logs state ?

I would need to request my security team to allow me to collect the log out from the jumphost.

To Try again, could i power down and delete the failed vcenter appliance? or any procedure of decommissioning the failed vcenter?

Power down failed vCenter and re-try.

but if it fails you will need the logs.

I've re-try. It turns out that the reverse dns for the PSC and Vcenter not added. Because the failed vcenter installation i entered the ip of the PSC instead of the FQDN.

After I removed the failed Vcenter from the PSC record, the installation was successful.

Forward and reverse DNS is very important to deploy PSC and Vcenter 6.0

VMware vSphere is ONLY as good as your NETWORKING, and this includes GOOD DNS!

so many functions are dependant upon good working DNS, e.g. VMware HA, vCenter Server, SSO, PSC etc
