VMware vSphere integration pack integration pack for VMware vSphere is an add-on for System Center – Orchestrator, it assists you in automating actions in VMware vSphere, enabling full management of your virtualized computing infrastructure.


After following the article https://docs.microsoft.com/en-us/system-center/orchestrator/vsphere-integration-pack?view=sc-orch-2019 to integrate the VMWare with SCORCH had an issue while trying to use the “Get VM List” properties and got the below error.


Exception: IntegrationPackException


I had tried to capture the traces but didn’t find anything.

So, tried to check the connection outside Orchestrator application using the Connect-VIServer cmdlet but it immediately fails with:



PowerCLI C:\Program Files (x86)\VMware\Infrastructure\vSphere PowerCLI> Connect-VIServer vCenter.lab.com

Connect-VIServer : 02/08/2020 11:41:37 AM Connect-VIServer The underlying connection was closed: An unexpected error

occurred on a send.

It was failing due to TLS error. From Vcenter, it was TLS 1.2 only enabled while TLS 1.0 and 1.1 is disabled by default.
