我试图评估Kafka融合平台4.0版。但是，当我在kafka集群上启用ssl时，kafka连接无法启动。
详细记录如下：

bin/confluent status
connect is [DOWN]
kafka-rest is [UP]
schema-registry is [DOWN]
kafka is [UP]
zookeeper is [UP]我错过了什么额外的配置？
请告知？

在kafka集群上启用安全选项后，需要为kafka connect workers启用等效的选项。
例如，对于基本ssl配置，您可能需要设置如下内容：
你的工人的配置(要像上面所示尝试使用confluent cli，此文件是
./etc/schema-registry/connect-avro-distributed.properties)您可以在此处阅读有关如何设置kafka connect with security的更多信息：
https://docs.confluent.io/current/connect/security.html
并在此处查找有关连接工作程序的所有可用安全相关属性：
