我有三个经纪人( brker1 , broker2 以及 broker3 )，我的Kafka马槽可以连接到 broker2 但无法与剩下的两个经纪人取得联系( broker1 以及 broker3 ). 我重新开始 kafka-manager , broker1 以及 broker3 同样，但仍然没有连接到这两个经纪人。
注：Kafka在3个经纪人身上运行
这个日志是我从 kafka-manage ```

我正在使用 `kafka-manager-1.3.2.1` 3个代理（代理1、代理2和代理3）正在运行
这是我从broker1获得的日志（kafka manager无法连接到此broker）
