Remote Desktop connection errors often arise because of various configuration or network issues. These are some of the more probable causes for Remote Desktop connection errors in Windows 11:
Remote Desktop isn’t enabled: The first thing to check if Windows 11 RDP (Remote Desktop Protocol) is not working is if the feature is turned on for the host and client PCs. Enabling it on Settings and the Services app should fix this.
Faulty Windows update: If the Windows 11 Remote Desktop is not working after an update, the problem is most likely caused by the update. The solution here is toremove the problematic updateor edit your registry.
What can I do if Remote Desktop isn’t working in Windows 11?
1. Edit your registry
Press theWindowskey +R, typeregedit, and clickOK.
Follow the path below in the left pane:Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services\Client
Now, right-click theClientfolder and chooseNew>DWORD (32-bit) Value.
TypefClientDisableUDPas the name of the new item.
Finally, double-click it, set itsValue datato1and click theOKbutton.
If you started noticing that the Windows 11 Remote Desktop is not working after installing the 22H2 update, it is because the feature is trying to connect with UDP.
The solution here is to disable UDP by creating a new registry value.
2. Turn off UDP in Group Policy
Press theWindowskey +R, typegpedit.msc, and clickOK.
Navigate to the path below in the left pane:Computer Configuration > Administration Templates > Windows Components > Remote Desktop Services > Remote Desktop Connection Client
Now, double-clickTurn Off UDP On Clientin the right pane.
Finally, tick theEnabledradio button and clickOK.
This is another excellent solution if the Windows 11 Remote Desktop feature stops working after the 2022 update. With the above steps, the UDP client should be completely disabled and allow your PC to connect.

5. Allow Remote Desktop through Windows Defender Firewall
