Ciphers used by Apple services like ABM?

Does anyone happen to know which ciphers Apple uses for their HTTPS connections for integration services? I was having issues setting up DEP on our Windows Server test instance, and enabled all ciphers just to get it to connect to Business Manager (it was previously unable to connect), but I'd rather not spend a couple hours toggling/rebooting/testing to see which one did the trick (so I can disable the couple dozen that weren't needed).

Edit: I did the work, once I enabled this cipher suite (using an app like IIS Crypto if you aren't a registry fan), I was able to connect with ABM for DEP:

Edit: And now it's not working anymore, so I'm not sure what to make of it.
