Network share Bare Metal Restore not seeing images

My 2012 Essentials R2 server is backed up to an ISCSI drive. Yesterday both disks in my RAID0 decided to die, so I am having to do a BMR from the backup. Steps I have taken:

1. New RAID0 logical drive created with two new identical disks
2. Mount ISCSI drive on my PC, give it a drive letter, and share the drive with Everyone having full permission on the share
3. Boot from 2012 Essentials R2 media on server
4. Choose System Image Recovery
5. Choose Advanced and specify network share location on my pc
6. Enter credentials when requested for the connection
7. Message appears with Scanning for system image disks
8. The list is then empty, no images are found?!?

The connection to the share is working as far as I can tell, if I enter an erroneous path it errors with path not found.

Why is it not listing the backup image?? I can see the vhdx files in the backup folder under WindowsImageBackup.
