Unable to connect to the server: dial tcp: lookup <first control plane node ip> on <dns server ip:53>: no such host

When i was trying to install the SMAX suite.

At the Prepare stage when it tries to deploy worker nodes it fails and gives a similar error like the one in the title at the install.xxxxxxx.log of worker nodes.

I checked with nslookup, dns resolution works just fine. But i also had a warning while running pre-check.sh script. What can be the problem here? Should i just start a clean installation?
