If you get the error " Connection has been closed. Another user may have logged in on the remote windows machine" while doing RDP into the remote windows server, then 'right click'->'inspect'-> click Console tab as show in the image below.
In order to overcome the error " NODE_RDP_PROTOCOL_X224_NEG_FAILURE()", ensure that Network Level Authentication is disabled for RDP under Control Panel->System->Remote settings
