It is happening because you have changed hostname from whm. In case of
VPS Hosting, hostname needs to be set from main node. I have set the hostname to
midlands.genservices.co.uk and corrected the entries in /etc/hosts.
Now it is working fine.
-----------------------------
-bash-3.1# host midlands.genservices.co.uk
midlands.genservices.co.uk has address 92.48.97.208
