macOS High Sierra internet recovery is frozen
This is why it is better to first download macOS from the Apps Store to your Applications folder. You then can create a USB flash drive installer for offline installations. The instructions are given at this Apple website: How to create a bootable installer for macOS.

You have already erased your drive so this is no longer an option on your Mac. In your case, you would now need another Mac to download High Sierra and make the installer.


  FYI: I usually have two installations of macOS per Mac. Each installation is in separate partitions. I usually the edit the /etc/fstab file so each installation can not access the other installation, unless I do a mount. This way I usually can avoid having to use macOS Recovery.
