We're experiencing the same issue in Central Canada as well randomly for some of our customers. Our error is also ConnectionFailedClientDisconnect (-2147467259). Also have a ticket open with Microsoft but have gotten no where with this. This is occurring daily for some of our customers randomly throughout their environments. Has anyone gotten anywhere with this?

    We've been pushing our customers to patch their devices and update to the latest Remote Desktop Client and it seems the disconnects have been rare to non existent since the updates have been applied. Not sure if anything has changed on the AVD side or if the client side updates have made the difference in our case.

      Having the same issue with a UK South AVD with circa 150 Users and 8 Session Hosts. Some users just get constantly disconnected we have checked and no local internet Issue. We have been suggesting to affaected users to use the "WebClient" not the Installable AVD Client and this is much more stable.

        Yesterday I had a MS Teams screen sharing session with Azure support. The issue seems to be related to the Azure Virtual Desktop Client that is trying to connect over UDP, instead of TCP.  By default the client now assumes that RDP shortpath is enabled.

         

        Some customers report issues and others not, possibly related to the firewallbrand. 

         

        As a workaround, TCP connections can be enforced on the client-side via GPO.

        Browse to Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Connection Client. Open the policy setting Turn Off UDP On Client and set it to Enabled.
