Failed to open source VMDK VDDK Error: 3014: Insufficient permissions in the host OS

Hello,

I'm trying to backup a list a Vms using Networker 18.0.2. For some Vms not for all Vms, I have got the following error:

Failed to backup virtual disk "Hard disk 2". Failed to initialize Block Reader. Failed to open source VMDK '[Datastore-xxxxxx] xxxxxx.vmdk': VDDK Error: 3014: Insufficient permissions in the host operating system.

And from the Vproxy logs I found the following messages:
