Why can’t I install macOS Big Sur over the network? Error 2002f

I’m trying to do a clean install of macOS Big Sur with a network boot (Catalina won’t boot due to some error), but after a few minutes of waiting, I get error 2002f. How to fix it?

We’ve covered all the ways to update your operating system to macOS Big Sur on any compatible Mac. If you are forced to stop at the network system restore, you may encounter errors while downloading Apple servers’ data.

Users have encountered this error all over the world for several years. The thing is that during the recovery, the computer downloads data from Apple servers and performs a remote check for binding to a specific Apple ID account. The error occurs exclusively in the second case, but the download will not continue without it.
