Hi All,

While adding connection and resources hosting for Nutanix AHV I am getting below error.

I have checked that all services are OK and not found any error in monitoring.

Have you installed the Nutanix plugin on the Delivery Controller(s)?

Follow this guidance when using Nutanix Acropolis to provide virtual machines in your XenApp or XenDesktop deployment. The setup process includes the following tasks:

• Install and register the Nutanix plugin in your XenApp or XenDesktop environment.
• Create a connection to the Nutanix Acropolis hypervisor.

yeah installed latest plug-in on both DDC, registered plug-in and verify that Custom Nutanix AHV is showing in Get-HypHypervisorPlugin
