安装kibana7.5.2报错Unable to connect to Elasticsearch.

elasticsearch版本：7.5.2
kibana版本：7.5.2
这两个安装包都是下载tar.gz包解压安装的
两个节点（我也知道最好三个。。可是目前机器就只有两个）
elasticsearch集群可以正常启动，遇到标题的错查了一下百度说加以下配置，可是我本来就加了：
network.host: 0.0.0.0
http.port: 9200
 
Kibana的kibana.yml我也是设置
server.host: "0.0.0.0"
 
设置好之后直接到bin目录./Kibana启动，然后发现连接不上显示以下错误：

文字版：

两个连接不上的错误，然后再循环显示下面的警告，后来我直接就关了。请问又大神可以帮一下忙吗？百度找不到解决的方案
