Nameservers not registered

I see no problem… your site looks fine and is clearly a selfhosted domain ?? You’re good.

Did you PURCHASE your domain via wordpress.com or your webhost?

Thank you for reply.

It is NOT doing good. Let me tell you little history. I had a shared hosting plan earlier with my hosting company. Than I purchased a VPS for me and wanted to bring my domain to this virtual server. That’s where the problem is.

I am unable to update my nameservers to point it to towards my server. I am handling my domain from that shared hosting so far, that’s why everything is fine apparently but i’ve received several emails since I setup my VPS with the following content:

Your hostname (vps.pakistanexaminer.com) could not be resolved to
an IP address. This means that /etc/hosts is not set up correctly,
and/or there is no dns entry for vps.pakistanexaminer.com. Please
be sure that the contents of /etc/hosts are configured correctly,
and also that there is a correct ‘A’ entry for the domain in the
zone file.

Some or all of these problems can be caused by /etc/resolv.conf
being setup incorrectly. Please check that file if you believe
everything else is correct.

You may be able to automatically correct this problem by using the
‘Add an A entry for your hostname’ option under ‘Dns Functions’ in
your Web Host Manager.

And yes, I purchased my domain via wordpress.com and how it is self-hosted wordpress site.

https://www.pakistanexaminer.com, is fine though, as I said. You didn’t mention subdomains being borked ??

Clearly you were able to point the DNS correctly at some point. Do you remember how you did THAT?

IIRC all the directions you need are here: https://en.support.wordpress.com/domain-mapping/domain-management/

They even link you to the CUSTOM DNS section, which is what you need
https://en.support.wordpress.com/domain-mapping/custom-dns/

I followed instructions given on mentioned links but still no success. I am unable to point my domain to my virtual private server. Current DNS are NS81.MOCHAHOST.COM and NS82.MOCHAHOST.COM, which I added last year, now I want to replace them with ns1.pakistanexaminer.com and ns2.pakistanexaminer.com. But still it is giving error ‘nameserver not registered’. Please advice how to fix the issue or refer me to relevant person.

What’s in your DNS values?

Looks something like this:

MX <pref> <host>.
TXT <text>
CNAME <subdomain> <host>.
A <subdomain> <IP>

Yours would include (I THINK! THE IP MAY BE WRONG!!!!)

A ns1.pakistanexaminer.com 204.93.196.222
A ns2.pakistanexaminer.com 204.93.196.222

or

A ns1 204.93.196.222
A ns2 204.93.196.222
