Question
Dns issue - Host domain.tld not found: 2(SERVFAIL)
[My level of knowledge with vps , linux and bind dns settings are at learning/begginer stage]
-
Added domain/PTR plugservice.com to droplet with ip 139.59.78.183.
-
Then somehow setup a vanity nameserver named ns1/ns2/ns3.plugservice.com pointing to ns1/ns2/ns3.digitalocean.com. Hope it is working fine.
-
Afterwards added a user account called michaelco.in through CWP. But domain was not reaching the droplet. So issued #Host michaelco.in and received “Host michaelco.in not found: 2(SERVFAIL)” error.
Can anyone please help me to fix the issue?

The issue is solved. It was due to missing A records for NS1/NS2/NS3 vanity nameservers in the droplet’s DNS manager.
