See this Apple article: If you see an error when you update or restore your iPhone, iPad, or iPod

If you see an error when you update or restore your iPhone, iPad, or iPod - Apple Support (SG)

Guess you use a Windows PC, if so check the AV & Firewall you use on the PC. 

Disable all AV & Firewalls temporarily while you restore & update your apple device.

If they are On, turn Off Hotspot & VPN.
