Server could not be contacted Mojave
So I am selling my 2018 Mac Mini, which runs OS Mojave. I did the command/option/R on the boot so that I could wipe my disk and reinstall MacOS. Unfortunately, I keep getting the error that the server could not be contacted. I have made sure that I have a healthy internet connection and that the time is synced in Terminal. Still no luck and I can't find any other solutions. Please help
Mac mini, macOS 10.14
