I am trying to use Kafka.
All configurations are done properly but when I try to produce message from console I keep getting the following error

WARN Error while fetching metadata with correlation id 39 :
     {4-3-16-topic1=LEADER_NOT_AVAILABLE} (org.apache.kafka.clients.NetworkClient)

Kafka version: 2.11-

It could be related to advertised.host.name setting in your server.properties .

What could happen is that your producer is trying to find out who is the leader for a given partition, figures out its advertised.host.name and advertised.port and tries to connect. If these settings are not configured correctly it then may think that the leader is unavailable.
