Hi,
from what kind of PC have you tried to install it?
This sometimes happens.By was it from Mac, bu I have it one time also on Win. Try to install it again and check double if you have all settings correctly. The biggest problems is doing the NTP and FQDN (check if you have also PTR set). if doesn't help, then try to install lower version (one update lower). All these helped me to install it.
When not, then try to install a new clean version if this works.
