vCenter refresh button keeps spinning without any action being performed.
vCenter Server 8.0.x
The issue is caused by being joined to the VMware Customer Experience Improvement Program (CEIP), but having all VMware sites/internet access blocked.
The issue is fixed in 8.0U3 and above versions
Workaround:
To resolve this issue, leave the CEIP and restart the vCenter server to clear up the issue.
