Check your security software
Related errors: 2, 4, 6, 9, 1000, 1611, 9006. Sometimes security software can prevent your device from communicating with either the Apple update server or with your device.
Check your security software and settings to make sure that they aren't preventing a connection to the Apple servers.
Check your USB connections

If the USB connection between your device and computer is interrupted, you may be unable to update or restore.
To narrow down the issue, you can also change up your hardware:
- Use the USB cable that came with your device, or a different Apple USB cable.
- Plug your cable into a different USB port directly on your computer. Don't plug it into your keyboard.
- Try a different computer.
- If necessary, resolve any further issues with the USB connection, then with your security software.

Has the software on your phone been modified in the past?
Check your hosts file
After you update iTunes to the latest version, check the hosts file to make sure your computer can contact the update server.
If you’re using a Windows computer, follow the steps in this Microsoft support article (note that resetting the hosts file will affect software services that rely on hosts file redirects). If you're using Windows on a business computer, consult your IT department to be sure applications will work correctly after you reset the hosts file.
