We’re having trouble getting the Generic Kafka Producer to start. Our Generic Kafka Consumer works fine using the same broker address and same SASL/PLAIN credentials, but the Producer fails during startup with:

<code>Confluent.Kafka.KafkaException: Local: Broker transport failure
(occurs during AdminClient.GetMetadata())
</code>

In Cube, we also configured an SNMP Manager (Apps → System Center → SNMP Forwarding) and selected that forwarder when creating the Producer element — but the Kafka connection still fails. We’re unclear what that SNMP Manager setting is actually used for in the context of the Kafka Producer.
