Team,  
We would like to replicate data from MirrorMake2 to Confluent Cloud.  
Our setting:

```auto
        bootstrapServers: "pkc-epwny.eastus.azure.confluent.cloud:9092"
        config:
         sasl.mechanism: PLAIN
         security.protocol: SASL_PLAINTEXT
         sasl.jaas.config: org.apache.kafka.common.security.plain.PlainLoginModule required username=' ***' password='***';

```

Issue:

```auto
2022-02-28 19:00:13,568 ERROR Stopping due to error (org.apache.kafka.connect.cli.ConnectDistributed) [main]
org.apache.kafka.connect.errors.ConnectException: Failed to connect to and describe Kafka cluster. Check worker's broker connection and security properties.

```

The issue happens when connecting MM2 with Confluent (SaaS).  
We would appreciate any feedback

It uses SASL\_SSL as the security.protocol. How can I configure the Confluent cloud to use SASL\_PLAINTEXT.
