A possible solution is to do what @kernix suggests, make sure your bitching corporate firewall isn't trying to mug you off. Are your ports open?
Another solution is to user Application Loader instead.
Open Application Loader, got to preferences (⌘+,) and unselect Signiant and Aspera, but leave DAV selected.
The problem was that I was using a university network which has a number of restrictions on servers as well as uploading and downloading. The only fix for this problem was to find another Mac to use which wasn't restricted.
After having the same issue I've been able to fix this issue.
To solve this issue you need to:
Go to page 6 "System and Network Requirements" from https://itunesconnect.apple.com/docs/UsingApplicationLoader.pdf
verify that all of the ports and IP addresses are accessible.
After opening all of the ports from the table, I'm now able to upload my apps.
Enjoy!
