DNS Server DNS address could not be found.

I'm unable to load my site domain2.com, I don't know what I've done wrong.

1) I set up hostname in the server, ns1.domain.com
2) I created a ns1.domain.com A record in CloudFlare domain.com account and pointed it to the server IP
3) I pointed the domain (domain2.com) to ns1.domain.com and ns2.domain.com (the domain registrar required a 2nd DNS)
4) I created a ns2.domain.com A record in Cloudflare and pointed it to the server IP

However, domain2.com doesn't load. What did I do wrong? Basically I want to point domain2.com to domain.com DNS

These are the results of intodns.com domain test

I'm so sorry Eva, I'd appreciate an example since I don't get it.
Let me tell you what I currently have set up:
1) Domain.com points to ns1.domain2.com and ns2.domain2.com
2) Domain2 DNS are managed by CloudFlare. An A record has been set up for ns1 and ns2 pointing to centminmod server.
3) I already created the nameservers in domain2.com registrar and pointed them to centminmod server.

 

sorry, I edited the post while you where posting. Actually I already created the nameservers (ns1 and ns2) in domain2.com domain registrar and pointed them to centminmod server

 

Ns1.domain2.com should be propagated already, more than 24 hours have passed. ns2.domain.com was just created

 

Do you usually experience issues like this one? Maybe the .xyz domain extension is a bit tricky? Domain.com actually is domain.xyz

Don't know if it helps but this is the content of
/usr/local/nginx/conf/conf.d/domain.xyz.conf

Cloudflare has replied and I'm still confused since I want to manage DNS through CloudFlare and not through the server by using BIND or NSD https://community.centminmod.com/threads/domain-name-dns-setup-on-local-nsd-server.855/

 

Their reply wasn't helpful at all:

 

I have a blog network and I want to use CloudFlare to set the dns (alpha.domain2.com and alpha.domain.com) and hide the server IP since it was affected by a DDoS attack recently so I want to use CloudFlare to set the nameservers.

Since I have many domains I want to point them to the DNS in CloudFlare (they are too many to add them to CloudFlare)

 

ohhh...too expensive. They are more than 20 blogs :/

Is there any other CloudFlare alternative I can use to hide the server IP?

 

How would it work?
The DNS points to the server IP, if anybody ping that DNS he will see the server IP
