I'm not sure if this'll answer your question, but I've found that when a calling a web service synchronously, which returns a 401 "Not authorised" error, iOS will simply return a vague -1012 error.

iOS: How can i receive HTTP 401 instead of -1012 NSURLErrorUserCancelledAuthentication

So, try to check whether you're having authentication problems, and tackle the problem from there.
