No resolvable bootstrap urls given in bootstrap.servers

Hi I have followed your instructions. But I am unable to make my connect up. Its exiting with error: Removing server monitoring-kafka:29092 from bootstrap.servers as DNS resolution failed for monitoring-kafka. monitoring-kafka is my kafka advertised host name. Could you suggest on it?

Hi Everyone,

Problem resolved after giving it a another name and building again the image.
