It looks like broker nodes are not able to understand SSL requests coming from the client. log.flush.interval.messages=10000 3- I installed kafka created a values.yaml with those values inside: And it is working without problems.

When it's nil, the listeners will be configured I am still facing the same old issue, Attaching complete pod logs for reference. With those values to empty, you are going to disable the server host name verification. Pls share me the right steps and commands to create the truststore and keystore secrets and creating multiple keystore for different kafka pods. log.retention.check.interval.ms=300000 If on the other hand you are within AWS lets say, you can then issue ip-XXXXX.ec2.internal:9993 and the corresponding connection would be plaintext as per the protocol map. Since the protocol map for EXTERNAL is SSL this would force you to use an SSL keystore to connect. However, the returning URL to use with the Group Coordinator or Leader could be 123.compute-1.amazonaws.com:9990* (a different machine!). tlsEndpointIdentificationAlgorithm: "https", can you share us the correct steps, So that I can cross verify with what I have used for creating the .jks certificates and secret. I suggest you to take a look this section: https://github.com/bitnami/bitnami-docker-kafka#configuration. Well occasionally send you account related emails. socket.request.max.bytes=104857600 If the client uses XXXXX.compute-1.amazonaws.com:9990 to connect, the metadata fetch will go to that broker. log.retention.hours=168 Can you please suggest me what values I need to use for these 2 attributes log.flush.interval.ms=1000 We followed the exact steps, as mentioned above and got the Kafka and Zookeeper pods up and running. values.zip Deployed the helm chart using these values and getting below error endpointIdentificationAlgorithm: "https" I will come back soon with feedback. function gtag(){dataLayer.push(arguments);} Seems that it is crashing for something in the configuration. And I can not reproduce any problem with the SASL. Is that the bitnami Helm Chart without modifications?

Hi @manjunath-vuyyuru , These consumers retrieve the broker registration information directly from ZooKeeper and will choose the first listener with PLAINTEXT as the security protocol (the only security protocol they support).
