Microsoft is investigating user reports of issues with Remote Desktop on Windows 11 systems after installing the Windows 11 2022 Update.

Installing the Windows 11 22H2 feature update will cause Remote Desktop clients not to connect, randomly disconnect, or freeze unexpectedly.

"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," one Windows admin said on Microsoft's Community site.

"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."

"Windows 11 22H2 breaks Remote Desktop connections via a gateway. Seems a pretty big issue to me, which apparently was reported. Why was something like this not fixed before release?" another user tweeted.

"I have several clients on Windows 11, and after the update 22H2, they were not able to log to our RDS servers. I tried without the firewall, nothing changed. The problem disappeared after the rollback, they have been able to log back in," a third one said on Microsoft Q&A. After installing Windows 11 22H2, others reported experiencing remote desktop frequent disconnects, remote virtual desktop not working, Remote Desktop Services failures, and Remote Desktop published apps issues.
