I have a single Windows 2012 R2 RDS server, which acts as all the RDS roles, including RD Gateway.
I also have an Windows 2012 R2 IISARR server setup to reverse proxy 443 connections to the server.
The problem is that on the RD Gateway, the HTTP & UDP connections disconnect every 2-5 minutes. The client screen goes black and a Reconnect Attempt 1/20 windows is displayed. Each time though the connection re-establishes itself and the session is
In the gateway manager, monitoring page, you can witness these connections disconnecting and re-connecting. It's very puzzling. The event logs acknowledge the disconnect, stating reason 0.
However, If I bypass the IISARR server, the connections are stable and don't disconnect.
So the question is, what does ISSARR do to disrupt the connection and how could I troubleshoot this?

You can try using Failed Request Tracing Rules to Troubleshoot Application Request Routing (ARR). For more information, you can refer the document:

Hope it can help you.
