Leader Not Available Kafka in Console Producer

Question

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 Err         


        

Answer 1

For me, it was happen due to a miss configuration
Docker port (9093)
Kafka command port "bin/kafka-console-producer.sh --broker-list localhost:9092 --topic TopicName"
I checked my configuration to match port and now everything is ok
