Unable to use Win10 RDP (running in Parallels for Mac) to connect to remote Win10 PC

I have a client running a Win10 VM that I need to RDP into for work. I have been doing this using Microsoft's Remote Desktop for Mac app but it is not the best app so I was hoping that the experience using Win10's RDP app accessed from within Parallels would be much better. When I attempt to connect using the Win10 RDP client an error is returned that it can't connect to the remote client (screen shot attached).

I can ping the remote computer from the command prompt and I can RDP to it using Microsoft's RDP for Mac so I know the computer is working. I also disabled the Windows Defender firewall thinking it might be blocking things. Again no luck.

Any thoughts?

 

Hi,
Did you ever find a fix or a cause? I just built a computer with Parallels and have tried Windows 7, Windows 8.1 and Windows 10 and I am experiencing the same issue.
