我试图设置mongodb源连接器[https://www.confluent.io/hub/mongodb/kafka-connect-mongodb]合流kafka平台。当我使用MongoDBAtlas的连接URI时，我能够成功地建立mongodb和kafka之间的流。当我使用mongodb运行在我的azure kubernetes集群上时，问题出现了。我创建了一个mongodb statefulset，有3个副本，我通过负载均衡器将mongodb服务公开到互联网。我能够通过使用robo 3T连接到公共IP上公开的mongodb，并进行CRUD操作。现在，当我使用在kubernetes中运行的mongodb的连接URI时，它看起来像“mongoDB：//load-bal-ip： 27017/test？ssl=false

INFO无法恢复更改流：$changeStream阶段仅在副本集40573（com. mongob.kafka.connect.source.MongoSourceTask：253）上受支持

mongo db有状态集yml看起来像这样

apiVersion: apps/v1

mongoDB服务中心是这样的

apiVersion: v1
kind: Service
metadata:
  name: eic-mongo-mongodb
 ports:
  - name: "27017"
    nodePort: 31683
    port: 27017
    protocol: TCP
    targetPort: 27017
  selector:
    app: eic-mongo-mongodb
  type: LoadBalancer

有人能告诉我哪里出错了吗？
