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

Turn your iPhone on and unlock it -> enter the passcode.

Go to Settings -> Display and Brightness -> Auto-Lock set to Never.

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.

Turn Off Hotspot.

Turn Off or remove VPN if necessary.
