Hello Team,

I am trying to work with a SSL based kafka topic.
I have setup the properties on Kafka producer node and ran the below commands for setting up keystore and trustore where my kafka certificates are stored.

mqsichangeproperties TESTNODE_z0019z5 -o BrokerRegistry -n brokerKeystoreFile -v C:\Git\das_egiftcard_publisher-v1\keystores\keystore.jks
mqsichangeproperties TESTNODE_z0019z5 -o BrokerRegistry -n brokerTruststoreFile -v C:\Git\das_egiftcard_publisher-v1\keystores\trustore.jks
mqsisetdbparms TESTNODE_z0019z5 -n brokerKeystore::password -u temp -p changeit
mqsisetdbparms TESTNODE_z0019z5 -n brokerTruststore::password -u temp -p changeit

Restarted the node after these commands.

I can see error in event log after I publish

Failed to initialise Kafka output connector. Reason ''Failed to construct kafka producer''.

Initialising the Kafka output connector failed with reason ''Failed to construct kafka producer''. Possible causes are:
1) None of the Kafka servers defined in 'Bootstrap Servers' property can be contacted.
2) If using an SSL connection, the SSL configuration is incorrect.
3) If using SASL authentication, the credentials are incorrectly configured.
4) The Kafka client could not be loaded.

Verify the Kafka servers are available at tha addresses specified in the 'Bootstrap Servers' property. If connecting to Kafka using an SSL connection, verify the SSL configuration properties match those required by the Kafka server. If connecting to Kafka using an SSL connection and have configured a SSL truststore, verify the truststore contains certificates which can validate those provided by the Kafka server. Further information on the cause of the failure may be available by enabling more detailed logging from the Kafka client in the log4j properties file.

From these properties only thing I can think of is SSL properties. IS there some other command/step which is missing.
