Remote Desktop Gateway frequent disconnects after KB5040430

Question

After installing KB5040430, we are seeing issues on the Server 2019 Remote Desktop Gateway on RDS.

All users get disconnected approximately every 30-60 minutes, and the following is logged in the Application log on the RD Gateway:

The system was operating normally before the Windows Update.

What steps can be taken to resolve this issue please?

Answer 1

Looks like this could be be fixed now in September's update, if I'm reading this correctly:

Key issues that this update addresses:...​​​​​​​***[Remote Desktop (known issue)]***Windows Servers might disrupt Remote Desktop connections across your company. This issue might occur if you use a legacy protocol in the Remote Desktop Gateway. An example protocol is Remote Procedure Call over HTTP. If the issue occurs, it is sporadic, like every 30 minutes. At that point, you lose sessions that you are signed in to. Then you must reconnect to the server. IT admins can track this as an end to the TSGateway service. It stops responding, with the exception code 0xc0000005.

Check out veloce-dragon post after their MS call. I haven't tried it yet or validated with my own MS call yet so buyer beware.
