Upload VM to the facilities

I'm trying to do a proof of concept. I have a simple virtual machine in the facilities with two VHD disks. I found links that tell how to prepare them for Azure. I have links that explain how to load the VHDs with PowerShell ADD-AzureRmVhd, they run for a couple of hours and then they fail with a file not found. Then I try to upload based on the web. It runs for a couple of hours and shows that the VHD is loaded and in my storage blog. I try to create a virtual machine to point to the file, but it does not say current files under subscription. Clearly it should not be as difficult as it seems. This is the link I am using. https://docs.microsoft.com/en-us/azure/virtual-machines/windows/create-vm-specialized#upload-the-vhd-to-your-storage-account Any help is appreciated.
