Hello akshort,
Thank you for using Apple Support Communities.
For more information, take a look at:

Resolve communication issues
Related errors: 17, 1004, 1013, 1638, 3014, 3194, 3000, 3002, 3004, 3013, 3014, 3015, 3194, or 3200. These alerts refer to gs.apple.com, say "There was a problem downloading the software," or say the "device isn't eligible for the requested build."
Check the hosts file or TCP/IP filtering, which might cause communication issues between iTunes, ports, and servers.
Have a nice day,
Mario
