Environment

VMware vCenter Server 8.0

VMware vCenter Server 7.0

Cause

Issue was because of the time taken for the information to be fetched from online and due to the time difference between the servers.

Resolution

Configuring the NTP on the vCenter Server to fetch time from the ESXi host it is residing on by changing the NTP setting of the vCenter Server from NTP Server to Host on the appliance management page/ VAMI page.

If above step doesn't resolve the issue , try to change NTP server to external server
