How do I fix 'recovery server could not be contacted' error when reinstalling macOS on an old Mac Mini?

I was wiping my old mini clean of info to give it way. While doing so I caught the power card and the Mini stopped of course. When I turn it on all I can get is utilities. But nothing seems to restore it. I have internet to it. Can access Apple on it. But when I try to re-install the software. I get this error message. "the recovery server could not be contacted". It's 10 years old. Could that be the problem. I can't supply what OS it was operating on or any details of the Mini because when I click on the Apple to get that info. Nothing is there. Do I just trash it with a hammer because I would be afraid someone could in fact access the hard drive and my personal info might still be in there somewhere. Thank you. Dave

As long as you encrypted that startup disk with FileVault, your personal information is impossible for anyone to retrieve without the encryption password: Encrypt Mac data with FileVault - Apple Support

If you chose not to enable encryption then follow the instructions in HWTech's posted link. For a brief summary of those instructions you may find High Sierra “The Recovery Server Could Not Be Contacted" Error. FIXED 2024 - Apple Community helpful.

Or, trash it with a hammer as you described, or an industrial shredder designed for the purpose, or use some other means of accomplishing irreversible physical destruction. https://nvlpubs.nist.gov/nistpubs/SpecialPublications/NIST.SP.800-88r1.pdf summarizes them as "Disintegrate, Pulverize, Melt, and Incinerate."
