Azure Virtual Desktop Random Client Disconnects
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.
- We are using EASTUS2 and user reporting the same disconnection.
Remote Desktop client 1.2.5112
Reason Web Client might be more stable is it uses TCP, the full client will use a combination of TCP/UDP.
What you can try is to turn UDP listener off on the session host and see if it any better.
UDP Shortpath will find the closest router to the session host from the client, it may be going over an Internal VPN where there may be issues with Bandwidth or the internal router isn't geared up for the traffic. We had to turn UDP off for one of our clients. However UDP for the majority of our clients have seen RTT improve.Web Client does not at this moment in time support UDP, which is why you get different reactions.

KevHal which version of remote desktop client are your users seeing the repeated disconnects with? 1.2.4065.0? we have a user seeing this after updating and suspect it's related to upd for him too - he fell back to an older version of remote desktop app and doesn't have the issue. Checking with Microsoft.
- Thanks for the advice above!.
