Hi Loaimohamed79 I see you cannot create the topics after enabling the TLS and it failed with the TimeoutException. Since you have enabled the TLS, 'listeners' property must be using SASL_SSL or SSL protocol and hence with the 'kafka-topics' command you will need to use the argument  --command-config and pass the client.properties file that includes the below properties, --- security.protocol=SASL_SSL OR SSL sasl.kerberos.service.name=kafka ssl.truststore.location=<truststore-location> --- So the command will look like, kafka-topics --create --topic demo --bootstrap-server 192.168.1.235:9093 --partitions 3 --replication-factor 3 --command-config <client.properties-file-location> Kindly follow these steps and let us know if it helps. ...
