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 als the AV & Firewall on the PC.

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

If they are On, turn Off Hotspot & VPN.
