We faced the same situation, when we started to search the logs for the actual cause of the error.

When we were starting the Kafka cluster, it was using by default

listeners=PLAINTEXT://:9092

to connect and was not able to find the host.

We changed the line to

listeners=PLAINTEXT:// :9092,

then

listeners=PLAINTEXT:// :9093, 

in our server-1.properties ( another broker id file ) and the same we replicated in other server.properties file and restarted our cluster.
