Follow the previous advise - First
Learned, a long time ago, to always have the Installation Media In-Hand before doing a complete Erasure of the drive
In this case High Sierra
Being Dependent on the Apple Recovery Servers for an operating system that was released in 2017 in 2025 would be iffy at best
Apple does usually have the Full Versionsof older operating systems but in this case you have to jump through hoops to get it
To perform this action will require booting from a Bootable Installer.
