Record this first — changing settings destroys the evidence

- Whether a VPN, firewall or security product is running
- The iPhone or iPad model and the version you were trying to install

ReversibleCheck that the computer can connect to Apple's software update servers.
Correct only the documented fault domain
ReversibleApple's steps: check that your computer can reach Apple's software update servers, and that third-party security software is not blocking the connection. Apple's steps to try first: install software updates on the Mac, or update iTunes or the Apple Devices app on a Windows PC, then follow the steps for your error number.
Update the computer
ReversibleInstall the latest macOS or Windows updates and the Apple app you use for the restore, since an old version may fail to contact Apple's servers.
Check the internet connection
ReversibleMake sure the computer is online. Load a few web pages and, if the connection is slow, restart the router.
Look in the hosts file
ReversibleOn a Mac or PC, check the hosts file for any entry naming gs.apple.com. An old entry there points the signing request to the wrong place and produces 3194.
Turn off security software for a moment
ReversiblePause the firewall or antivirus, try the restore again, then turn it back on. A VPN should also be disconnected.
Restart everything
ReversibleRestart the computer and the iPhone or iPad, and try a different USB cable and port if the first attempt failed.
Try another computer or network
ReversibleIf the restore works elsewhere, the first computer or network was blocking Apple's server, and you can fix that at leisure.
