打开vCenter网页显示no healthy upstream报错

解决办法：

1、使用SSH访问VSCA主机。

2、输入如下命令，检查证书有效期，发现__MACHINE_CERT证书到期。

for i in $(/usr/lib/vmware-vmafd/bin/vecs-cli store list); do echo STORE $i; sudo /usr/lib/vmware-vmafd/bin/vecs-cli entry list --store $i --text | egrep "Alias|Not After"; done

STORE MACHINE_SSL_CERT
Alias :    __MACHINE_CERT
            Not After : May 13 19:13:28 2023 GMT
STORE TRUSTED_ROOTS
Alias :    6a23dc81223746a515a85e9cca52764b2e3abb00

STORE machine

            Not After : May  8 07:13:28 2031 GMT
STORE APPLMGMT_PASSWORD
STORE SMS
Alias :    sms_self_signed
            Not After : May 13 07:19:47 2031 GMT
STORE wcp

            Not After : May  8 07:13:28 2031 GMT

3、执行如下命令重新生成证书。
