Validate that the vSphere permissions are properly configured. See Citrix eDocs - VMware and virtual machine management.
If the behavior persists, engage VMware to investigate vSphere failures.

Problem Cause

This error can occur because of improperly configured permissions for the vSphere user account that is tied to the XenDesktop Host Connection.
