Target Is Not Convertable To APFS

Hello everyone, I'm in need of urgent assistance. I accidentally erased the hard drive of my 2011 MacBook Pro. Now, when I try to reinstall the operating system, I receive an error message stating "Recovery server could not be contacted." My internet connection is working fine. After the reboot, when the macOS Utilities page appears, I encounter the same "Recovery server could not be contacted" error while attempting to install High Sierra. I've attempted to resolve the issue by changing the date and time using Terminal, both by going back to an old date and using the correct date and time, but neither solution has worked. Upon checking the error log for the OS Installer, I found the message "Target is not convertible to APFS, was called on an APFS disk: This volume is not formatted as Mac OS Extended (Journaled)." But the volume IS formatted as Mac OS Extended Journaled. Any assistance would be greatly appreciated. Thank you in advance!

If you have access to another Mac from Late-2009 to mid-2018, then you can create a bootable macOS 10.13 USB installer using the directions in the following Apple article:

Create a bootable installer - Apple Support


If you also have a 2011 model or older, then if you have access to another Mac from 2007 to 2015, then you can instead create a bootable macOS 10.11 USB installer.


Those model dates are just generalized so it is best to verify the other Mac is compatible with one of these two operating systems (the other Mac can currently be running any version of macOS 10.6+):
