WMI Issue with VM on hyperv host

We are facing a very strange issue with WMI on one VM running on a Hyper-V cluster

The VM is running veeam backup server and we got some random failing job backup

Troubleshooting the issue with veeam support we noticed that the jobs fails when the VM is running on node1 of the cluster , when is on node 2 the jobs are not failing


On further analysis we found that the WMI query that the veeam software executes on cim\root of the server   Node1 fails when the VM is running on node 1 itself and executes properly when is running on node2 


we test it with wbemtest 

does anyone have any idea on how to get it working ?
