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 2

Yep, we had the same with one of the clients. Remote Destop Gateway service was crashing every 2-5 minutes.

I removed KB5040430 and blocked. It looks like this cumulative update didn't affect any other severs.

Answer 3

That temporary solution was removed this week by the poster.

Beyond awaiting a permanent fix, we are still waiting for Microsoft to publicly acknowledge the problem

Answer 5

I have the same issue on Server 2019 and removing the KB5040430 patch stopped it. I believe that for me the service crashed anytime someone disconnected from the gateway since it could work for hours without issue and the crashing was sporadic.
