Remote Desktop stops working after installing Windows 10 20H2

I have been using Remote Desktop on my Windows 10 Professional for several months. It suddenly stopped working after installing Windows 10 20 H2 with the following message:

'Remote Desktop can’t connect to the remote computer for one of these reasons:

1) Remote access to the server is not enabled
2) The remote computer is turned off
3) The remote computer is not available on the network
Make sure the remote computer is turned on and connected to the network, and the remote access is enabled.'

What causes RDP to stop working? How can I fix the Remote Desktop not working after Windows 10 upgrade issue? Any help would be much appreciated!"

  • The network of the host computer or the client computer (the computer where you start remote access) is poor.
