kafka queue ssl handshake

Hello
we are facing this issue in using the plugin "kafka-tools 1.0.1"

We have setup all parameters as indicated in the manual (see image above)

but  we got this message error in the tomcat-stdOut.log

2022-01-24 09:33:25,708 [kafka-producer-network-thread | producer-15] ERROR org.apache.kafka.clients.NetworkClient -

Do you know if and where in the Appian server we must edit some configuration for Kafka?  or do you have any suggestion or hint?

Thank you in advance, best regards
