Cant add domain.

[AlChrist]

Hello. Please help me, cause I am now just frustrated.

I have a VPS with 2 dedicated IP's. I got cpanel installed there.
I've created account in WHM, added package with unlimited domains.

My VPS hostname = name.domain.com.

At namecheap registrator:
name.domain.com - points to VPS IP1.
domain.com points to VPS IP1.
In Nameserver registration: ns1 - VPS IP1, ns2 - VPS IP2.

Now I have a domain that I want to add to cpanel.
At namecheap - transfer to webhost and I put my ns1.domain.com, ns2.domain.com

When I press "Addon domain" - I get:

Sorry, cannot determine nameserver IPs. Please make sure that the domain is registered with a valid domain registrar.

Allow unregistered domains - ON.
I am able to add domain, but it wouldnt open in browser, or ping.

Instead in browser opens up from opendns info:

Nameserver trace for newdomain.info:

Looking for who is responsible for root zone and followed i.root-servers.net.
Looking for who is responsible for info and followed a2.info.afilias-nst.info.
Looking for who is responsible for newdomain.info and followed ns1.domain.us.
Nameservers for newdomain.info:

ns1.domain.us returned (SERVFAIL)
ns2.domain.us returned (SERVFAIL)

info: real domains are replaced with "domain"/"newdomain"

Did you finish setting up WHM first?

Of course. It's a part of initial setup of WHM.

ns1, ns2 - IP's were assign, A entries too.

When I press again:

Basic cPanel & WHM Setup
This system has no free IPs.

Sadly, I tried it before.
