unspecified

I have it working now. I tested it on a fresh installation. The issue was resolved by installing the 'xauth' command: sudo apt-get update sudo apt install xauth After installing 'xauth', RDP connections from Windows worked as expected. I'm not entirely sure why this fixed the problem, but my hypothesis is that 'xauth' is required to add the authorization information used to connect to the X server and stored in the '.Xauthority' file.
