Hello,
I have this issue when migrating a 6.0 vCenter to 6.5:
Error
Host name vS-vCenter1.dpsi.jp is not DNS resolvable, but matches the machine certificates. If you do not configure a valid DNS resolvable hostname mapping, then you might not be able to connect to the vCSA afterwards
Resolution
Either update appliance /etc/hosts or /etc/resolv.conf file to properly access DNS servers or update appliance DNS servers with the proper host name mapping. To check if DNS server has record about local host name, execute `dig vS-vCenter1.dpsi.jp +short` locally on the appliance, or `nslookup vS-vCenter1.dpsi.jp` on a windows machine.
The commands suggested work as expected, and DNS records all resolve correctly.
What could the issue be?

There are no screenshots in my post but if you insist its the same as the above post...
On vCSA, can you 'dig -x 192.168.1.11'?
Are all hosts involved querying the same DNS server(s)? If you have more than one, 'dig @192.168.2.2 -x 192.168.1.11', for example. Make sure everything resolves forward and back everywhere.
root@localhost [ ~ ]# dig -x 192.168.1.11
; <<>> DiG 9.10.4-P1 <<>> -x 192.168.1.11

Only 1 DNS server which is 192.168.1.1 and it returns the correct results. Not sure why it isn't working.
