Why is this happening?

The

Server.properties

file in the Kafka Server is not properly configured as shown below:

#advertised.listeners=PLAINTEXT://your.host.name:9092

 

Solution

Add the Kafka Server's IP instead of the machine name in this setting and uncomment it, as shown below:

advertised.listeners=PLAINTEXT://10.xx.xxx.xxx:9092
