Error during restoration

Hello,

I've a big problem that I'll try to summarize. I've an infrastructure with a cluster of 6 VxRail. During a certificate regeneration with vSphere, we had an error and we lost the vmx file and vmdk files of the VMWare appliance which allows us to launch the vSphere. Avamar support told me that I had to disconnect the VxRail on which there's the Avamar proxy from the vCenter and then save it in Avamar instead of vSphere to restore the backup. I did this procedure but when I restore I get this error message :

Failed to initiate a backup or restore for a virtual machine because no proxy was found to service the virtual machine.

Check that proxy clients have the desired datastores checked for protection. The proxy client datastores checked must match datastores for virtual machines requiring protection. For scheduled group backups additionally verify that the group has desired proxies checked for protection of virtual machines belonging to the group. Verify proxy clients are powered on, enabled, and registered. For restores, verify there is an available proxy in the destination datacenter.

If you've an idea...

Thanks !
