what model MacBook Pro?

older Macs, before about June 2013 do not use "Apple Diagnostics" so when you try to get the diagnostic via Internet Recovery, it cannot be found and you get an error.

How to use Apple Diagnostics on your Mac - Apple Support

On your older Mac, the Apple Hardware Test will be found on the original-Installer DVD. If you need help finding a copy on the Internet, please post back.

Good luck!
