Apple Hardware Test or Diagnostics not working?

I have a Mac mini that I'm trying to boot up to Apple Diagnostics or Apple Hardware Test (holding down D or holding down Option-D while starting up). It will not work with either. I can get to the Apple Hardware Test screen, but it tells me my Mac is not compatible.

The only peripherals connected are:

Apple wired keyboard (USB port on Mac mini).
Apple wired mouse (USB port on keyboard).
Apple Display non-Thunderbolt (mini-display port on Mac mini).
Ethernet cable (ethernet port on Mac mini).

Mac mini details:

Mid 2010 - Macmini4,1
macOS 10.13.6
2.4 GHz Intel Core 2 Duo
8 GB 1067 MHz DDR3
NVIDIA GeForce 320M

Any relevant thoughts or suggestions?

How to use Apple Hardware Test on your Mac - Apple Support

Some Mac computers that shipped with OS X Lion v10.7 or later will start up from AHT over the Internet if your startup disk doesn't contain AHT, or if you hold down Option-D at startup. This requires an Internet connection over Ethernet or Wi-Fi.
If you're using OS X Lion v10.7 or earlier and you can't get AHT to start, see if you have an OS X installation disc named “Applications Install Disc 2.” Insert the disc in your internal optical drive or external Apple SuperDrive before following the steps above. Or, if you're using a MacBook Air (Late 2010), plug the MacBook Air Software Reinstall thumb drive into your USB port instead.

Thank you for the info macjack. Unfortunately, I don’t have access to the Apple install discs and I’ve already read that info and did not find it relevant. As stated in my original post, neither holding down the D key or Option+D during startup works. Both options get me to the AHT, but then displays a message telling me this Mac is not compatible with AHT.

If you've already tried the two options and you do not have the install disc, then you cannot run AHT. What problem are you having that you suspect may be hardware?

@macjack — no issue in particular, but just had a HDD fail and replaced with an SSD. So I wanted to use the AHT to check if there were any other hardware issues.
