I think I know what the issue is. Try shrinking the partition/volume on the computer that is used for creating the image before uploading. That way the partition that is restored is will be a few GBs less than what the computer you are trying to image to. I noticed when I was trying to image to identical computers the claimed to have the same hard drive space as the computer that the image was made on I had the same issue you had in the video. The computer doesn’t actually image FOG seems to just bail out and then the computer reboots.
Edit: An easier way to test this would be to throw in a hard drive that you for sure know is larger (not the same) than the hard that the image came from and then try imaging. Or even just use a different computer with a larger hard drive to test if the imaging process starts (even if the image isn’t built for that computer you can still do it just to test).
