1.How did you start the remote connection to windows 10? Did you remote via mstsc command?
2.Kindly check if remote access has been allowed in the target windows 10 computer.
· Make sure you have Windows 10 Pro. To check, go to Start > Settings > System > About and look for Edition. For info on how to get it, go to Upgrade Windows 10 Home to Windows 10 Pro.
· When you're ready, select Start > Settings > System > Remote Desktop, and turn on Enable Remote Desktop.
