perhaps… just perhaps…
Run the download in “debug” mode,
mount the SMB share manually at the CLI, and start the imaging process? (do not use the “fog” command, it tries to mount via NFS).
You’d have to dive into what the “Fog” command actually does… find it’s file and examine what is in it…
And just do everything in there except the NFS stuff (because you already mounted via SMB, right?) and cross your fingers and see if it works?
The "Troubleshoot NFS " article MIGHT assist you with some of this…

And the ill-completed Fedora 21 Server article has examples of SMB mounting…
https://wiki.fogproject.org/wiki/index.php/Fedora_21_Server
and, if you can figure out the commands to issue… and it works… then modify the “fog” command so that it does those things every time, then it should work for normal image downloads?
You’d have to modify the upload processes too.
I’d totally absolutely try this like right now but my servers are down due to a dead AC adapter for my router
