MacBook Pro 2016 stuck in internet recovery

The Problem

I recently wiped all my data from my MacBook Pro. For some reason, when I re-install macOS, it says: "An error occurred while preparing the installation. Try running this application again.

In the installer log, it says:

osishelperd[527]: Couldn't mount base system dmg! (error code 110)
osishelperd[527]: IATOOL: Failed to mount outer dmg
osinstallersetupd[519]: Unable to setup bless on disk.

I've tried maaaaaany things. I've tried Bootable USB Installers and alot of other things.

I've been trying to fix it for a few months now. Please help...

Start up from macOS Recovery

Option-⌘-R

Upgrade to the latest macOS compatible with your Mac.

In Disk Utility>View, select Show all Devices, highlight the top left entry.

Run Disk First Aid on all items in the left panel, from top down.

APFS won't work for Sierra or earlier, Sierra or earlier needs MacOS Extended Journaled. High Sierra won't work for APFS on earlier Macs.
