Issues with Remote Desktop on Windows 11 after Update 22H2

All of our Remote Desktop Users using Windows 11 are having problems connecting to Remote Desktop after installing this update. It just hangs at connecting.

We have found that there is a bug in the Remote Desktop client so that it is only trying the UDP connection and not trying TCP connection. We only allow the port 443 connection through on our firewall.

The only workaround we have found is to make the following change on the Windows 11 computer.

Have to set this value to 1 in the registry for Windows 11 client to work outside the network

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services\Client

KEY VALUE - fClientDisableUDP SET TO 1

Otherwise the Remote client just keeps trying to connect via UDP.

This issue did not start until the Windows 11 update was installed over the last couple days.

    Well I'm a home user and I have got the same problem - I work a casual job 2 days a week from home and cannot connect to the remote desktop after downloading the Windows 11 Update. How do I fix this?

    FrancineHold is right,- what if you are a home user and work remote from your home?...

    I got this problem today, exact in this case of working remote.

    The RegPatch worked. I think the problem is related to KB5018427, because since i installed that within the updates, it appears.

    I've done everything noted here and I'm still getting a 0x4 error when trying to connect over the internet.

    Connecting via local network is fine, though.

    I’m getting 204 error and this fix (on client laptop) did not work. Is that the same error you got? Do we need to make additional changes to Firewall? I have been working w Microsoft support for over 1 month and they have not helped at all

    Hi Jeff,

    Thank's for your analyse.

    We had the same issue, and your regedit/UDP workaround has solve our stuck.

    Now RDP are running fine with 22H2.
