我正在尝试连接到amazon管理的流kafka群集。我一直在遵循关于创建主题的教程https://docs.aws.amazon.com/msk/latest/developerguide/create-topic.html.
我的vpc安全组允许任何入站和出站流量，所以我不怀疑这会阻止连接。
我试过这个命令。

bin/kafka-topics.sh --create --zookeeper ZookeeperConnectString --replication-factor 3 --partitions 1 --topic AWSKafkaTutorialTopic

会产生令人不快的错误：

Exception in thread "main" kafka.zookeeper.ZooKeeperClientTimeoutException: Timed out waiting for connection while in state: CONNECTING
    at kafka.zookeeper.ZooKeeperClient.$anonfun$waitUntilConnected$3(ZooKeeperClient.scala:242)

    at kafka.admin.TopicCommand$.main(TopicCommand.scala:53)
    at kafka.admin.TopicCommand.main(TopicCommand.scala)

我做错了什么？需要什么配置来防止连接超时？
