NSURLErrorDomain error -1012

There is no error 1012 here http://support.apple.com/kb/ts3694

However I did find this Error -1002, 1011, 1012, 1014 These errors may indicate a hardware issue with your device. Follow the steps in this article. Also attempt to restore while connected with a known-good 30-pin Dock Connector cable, computer, and network to isolate this issue to the device. The MAC address being missing or the IMEI being the default value (00 499901 064000 0) can also confirm a hardware issue in this article http://www.globalgsm.mk/thread-2559.html

In the knowledge base note I sent you there doesn't appear to be an error 1012. That does not mean that you didn't get it... it just means that it is not a specific apple error hence I did a google search to see what I could find for that error code. If the link I gave doesn't solve things for you, you might also do such a search and see if you can find something that might help you.

I had the same problem whilst trying to activate updates through the App Store. I noticed that my Kaspersky Security was picking up the iCloud server as having an invalid security certificate, therefor disabled the security to see if the firewall was a problem. Sure enough, after disabling the firewall everything worked just fine.

It may be worth checking your firewall settings to see if it's the root cause?

Hope this works for you!!

Had this issue for a short while after repairing my iPhone. The answer was to set the time manually and then back to Automatic, now all apps working well again.

Hope this helps!

It sounds like you are getting a domain error when trying to log into the app. This is not at all associated with restore errors and does not indicate in any way a hardware failure. Something is wrong with the app or your network. If your other apps are working without any issues, I would see if you can log into the same app on another device or if another account can sign in to that app on this phone. The issue will likely need to be fixed by the app developer though.

I had this same problem, but it just turned out that the time on my iPod was wrong, so the security certificate had expired because my iPod thought it was Novemeber 2014, so check the date on your iPhone!

1. Try Settings the change your date to set automatically.
2. then go to WiFi, and find the connection you are connected too.
3. Then click the blue arrow on the right, and scroll down to Dns and erase all
4. After you erased all of the numbers, type in 208.67.222.222
5. click home and check if facebook or safari works,
6. if not, go back to Dns and try 8.8.8.8
7. then see if it works

im pretty sure it will work with one of those dns numbers
