1. 問題
重啟vcenter，登陸vsphere client，提示
“503 Service Unavailable (Failed to connect to endpoint: [N7Vmacore4Http20NamedPipeServiceSpecE:0x0000558181b429e0] _serverNamespace = / action = Allow _pipeName =/var/run/vmware/vpxd-webserver-pipe)”
2. 解決方法
重啟VCSA，vsphere-client服務還沒有啟動，需要稍等片刻。
如果長時間還是如此，則需要使用SSH登陸VCSA查看並解決問題。

啟動VCSA后，我們並不能立即進入。刷新瀏覽器后，VCSA會提示正在初始化。稍等片刻，再次刷新就會進入登錄界面。
