Answer 1

A host could have multiple dns aliases. Any of them would work for ssh or ping test. However kafka connection should use the alias that matches advertised.host.name in server.properties file of the broker.

I was using a different alias in bootstrap_servers parameter. Hence an error. Once I changed the call to use advertised.hostname, the problem was solved
