Hi,

I am creating an image with file folders to be uploaded into the Azure windows image.

What I have done so far. I have created a custom windows image with SSH server installed and running the below packer script to provision a new image from that custom image. Packer is able to create all the required resources at runtime but not able to upload any files to it and terminates with the error "Context deadline exceeded".
The same is achievable from winrm but failing with SSH.
Since the files and directories are huge in size so it is taking a lot of time to transfer using winrm that's why I chose SSH communicator to quicky upload the files but its failing.
