我在另一台机器上有一个3节点的kafka集群，我无法用spring启动应用程序远程连接和使用消息。我已将配置文件更改为：

advertised.listeners=PLAINTEXT://<myActual IP address>:9092

这是我的申请表

spring:
  kafka:
    consumer:
      bootstrap-servers: :9092,:9093,:9094
      group-id: test-consumer-group
      auto-offset-reset: earliest
      key-deserializer: org.apache.kafka.common.serialization.StringDeserializer
      value-deserializer: org.apache.kafka.common.serialization.StringDeserializer

运行应用程序时，出现以下错误：

2020-10-26 12:47:52.524 WARN 4524 --- [| adminclient-1]
