On the puppet master side:

How to resolve this?

Answer 1

You need to check you site.pp and make sure you either have a default node definition defined or a node definition for the FQDN of your agent.

https://docs.puppet.com/puppet/latest/reference/lang_node_definitions.html

for example:

node 'agent2-virtualbox.servicemesh.com' {
  import ntp
}
