Why won't my website upload onto the web?

Right, I have a site which I want uploading to the web via the Azure webhosting platform.

1) I established a remote server connection which came back with no problems when tested.

2) The Local Folder Directory is set to the Adobe Creative Cloud folder.

3) The Remote Server root directory is "/"

4) My default page is directly in the root folder of the remote server, where it should be.

So why then, won't my website upload when I hit the "Put" button, telling it to upload ALL files from the Local to the Remote Server? I dont understand how a computer, an inanimate object and programmed to do what the user tells it to, behaves like an awkward, disobedient child who won't do as its told?
