We bought two new blades recently. When my colleague tries to configure the vShield Endpoint on the two new hosts, he always get an error ‘Lost communication with ESX module’.
I SSH into the host, and checked the syslog. It complains the certificate is not yet valid. And I noticed that the time is not correct on the hosts. The time has been set back to more than a year ago. Now it makes sense – if the certificate is issue this year, of course the host will complain the certificate is not yet valid. As 2013 means feature to them
Correct the time settings does fix this issue.
