VCSA 6.5无法访问，报错“503 Service Unavailable”的解决方法

在访问VCSA间突然卡死，无法刷新，但是能ping通VCSA，过了好会儿，刷新浏览器，显示如下错误:

503 Service Unavailable (Failed to connect to endpoint: [N7Vmacore4Http20NamedPipeServiceSpecE:0x0000558181b429e0] _serverNamespace = / action = Allow _pipeName =/var/run/vmware/vpxd-webserver-pipe)

正在找解决方法的时候，突然不报这个错误了，又报一个同类的错误，错误如下:

503 Service Unavailable (Failed to connect to endpoint: [N7Vmacore4Http16LocalServiceSpecE:0x00007fbd38074bd0] _serverNamespace = /vsphere-client action = Allow _port = 9090)

解决方法:

使用SSH登陆VCSA查看并解决问题。

本机IP需要打通到宿主机EXSI管理IP和Vcenter管理IP所需端口
