I am trying to list topics on a Kafka cluster that is setup with no authentication. I am using the command line where b1 and b2 are broker names.

kcat -b b1:9094,b2:9094 -F kc.properties -L

My kc.properties is as shown below:

bootstrap.servers="b1:9094,b2:9094"
security.protocol=PLAINTEXT

I have tried without adding the “security.protocol” line as well.

However, I am getting the following error message:

Disconnected while requesting ApiVersion: might be caused by incorrect security.protocol configuration (connecting to a SSL listener?) or broker version is < 0.10 (see api.version.request) (after 38ms in state APIVERSION_QUERY

Brokers are on AWS MSK version 2.2.1
