I notice your connection type is “Apache Kafka Consumer Connection”. If you have the latest adapter fixes installed, there should be a type called “Confluent for Kafka® Consumer Connection”. I believe it has specific code and features for Confluent Kafka.
I was able to get that one connecting to Confluent Cloud, so I assume it would work with a local cluster as well
As Kasi mentioned, you also need to ensure the proper Confluent jar client libraries are in in the correct IS directories
