Restart PC and iPhone or iPad

Edit “hosts” file
You may have edited your hosts file before. For Windows users, go to C:/Windows/System32/drivers/etc/ and open hosts file. For Mac users, open the /etc/ folder and search for hosts file.
Open hosts file and scroll to the bottom. Check for any line that has gs.apple.com or other modification of apple.com. Once you see this, make a backup copy of this hosts file and put it on your desktop. Delete that line that contains the appe.com. Restart your iTunes and check if you can update your device already.
