我在一个云服务器实例中安装了一个Zookeeper和一个Kafka代理服务器，它们运行良好。但是，当尝试连接到远程Zookeeper服务器时，Kafka代理无法访问该IP地址和端口号。防火墙也处于非活动模式。
总结如下：
one zookeeper server - in cloud instance [146.646.64.66*]
one Kafka broker server - in cloud instance [146.646.64.66*]
two Kafka broker server - in my local PC [localhost]
我已经更新了本地Kafka代理服务器的属性文件的zookeeper.connect属性，如下所示：
zookeeper.connect=146.646.64.66*:2181
以下是CMD显示的错误：

请帮我解决这个问题。
删除所有缓存的日志文件或更改要运行的server.properties文件的日志路径目录。缓存日志文件的数据可能会受到服务器历史记录的影响。
