Sentinel监控画面为空白，后台报错java.net.NoRouteToHostException: 没有到主机的路由

之前Sentinel在本地跑没问题，今天放到centos服务器上跑，监控画面和簇点链路画面一直为空白，具体报错如下：

报错信息很清楚，没找到主机。。但是为什么会找不到主机呢？一看这个ip我发现不是我本机的ip。。cmd->ipconfig/all发现，本机居然有几个以太网适配器 以太网。。。到控制面板里把多的禁用掉后，再跑发现还是报同样的错，只是报错信息里ip变了，但ip还是不对，原来它找的是VMware Virtual Ethernet Adapter for VMnet8虚拟机的ip。。。好吧，全禁用掉。重启Sentinel服务后，问题解决。
