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

Guess you use a Windows PC, if so check all 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.
