It can’t connect to your Zeebe broker as it says in the exception message:

Connection refused: localhost/127.0.0.1:26500

You may need to configure it to point to your right Zeebe broker (or Camunda Cloud), see zeebe contact point: https://github.com/zeebe-io/kafka-connect-zeebe#zeebe-broker-properties
