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!"

Why is Remote Desktop not working after Windows 10 upgrade/update?
Windows Remote Desktop, known as RDP or RDS, allows you to connect to a Windows computer over the internet. Sometimes, you can meet RDP errors like" can't connect to the remote computer", "Your Remote Desktop Services session has ended", etc. after Windows 10 update. There are different possible causes of why Remote Desktop stops working and the most common types are concluded below to help you solve the issue.
- Remote Desktop hasn't been enabled on the host computer (the computer you need to access).
- RDP hasn't been allowed through Firewall.
- The network of the host computer or the client computer (the computer where you start remote access) is poor.
- The host's IP address has changed and the DNS resolver cache stores the wrong IP address.
