ns1.centos-webpanel.com Nameserver is not authoritative for foo.bar

I trust having set it up the right way but perhaps then not  Checking on leafdns

The parent nameserver c0.nic.me. reports your nameservers as
ns1.centos-webpanel.com. | Nameserver is not authoritative for foo.bar.
ns2.centos-webpanel.com. | Nameserver is not authoritative for foo.bar.
None of the nameservers listed by the parent nameservers are both responsive and authoritative for your domain. This error is fatal, and the domain is unresolveable.

I do not see how this an error on my end 

TTL 14400
foo.bar.      86400        IN      SOA     ns1.centos-webpanel.com. email.some.net. (
            2013071600      ; serial, todays date+todays
            86400           ; refresh, seconds
            7200            ; retry, seconds
            3600000         ; expire, seconds
            86400 )         ; minimum, seconds

foo.bar. 86400 IN NS ns1.centos-webpanel.com.
foo.bar. 86400 IN NS ns2.centos-webpanel.com.

I did not touch the NS IPs, both are at 127.0.0.1 and the info on top of the editor window reads

ns1.centos-webpanel.com resolves to 54.36.136.192
ns2.centos-webpanel.com resolves to 167.114.21.225

if you're using own nameserver change with :

TTL 14400
foo.bar.      86400        IN      SOA     ns1.foo.bar. email.some.net. (
            2013071600      ; serial, todays date+todays
            86400           ; refresh, seconds
            7200            ; retry, seconds
            3600000         ; expire, seconds
            86400 )         ; minimum, seconds

foo.bar. 86400 IN NS ns1.foo.bar.
foo.bar. 86400 IN NS ns2.foo.bar.

and change nameserver IPs :

ns1.foo.bar -> (IP)
ns2.foo.bar -> (IP)

Got only ip and reckon it is better to have at least 2 ip to serve DNS from. Hence I wanted to utilize

ns1.centos-webpanel.com 54.36.136.192
ns2.centos-webpanel.com 167.114.21.225

Is it my misconception that this is possible and those 2 servers are not open to CWP users?

it may not be smart anyway to advertise to malicious parties that CWP is utilized on the domain through a NS called 'centos-webpanel'...

Its always better to use private dns.

true. It was me being silly
