Azure Virtual Desktop Random Client Disconnects

Occasional Contributor



Is anyone experiencing random client disconnects in Azure Virtual desktop.


We have a deployment in UK South where clients frequently randomly disconnect for no apparent reason and we are certain is is not a local internet issue.


Microsoft support has not been helpful at all so far

Is your session host having Accelerated Networking ON or OFF?

No accelerated networking is switched OFF on all session hosts.
Hi - We are in the same boat in India region, experimenting with Accelerated Networking ON and OFF, Majority of the users getting ConnectionBrokenMissedHeartbeatThresholdExceeded error.
This is the error we have: ConnectionFailedClientDisconnect (-2147467259)
We get the same error ConnectionFailedClientDisconnect (-2147467259) as main error, but if you see the details of trace then you will find ConnectionBrokenMissedHeartbeatThresholdExceeded in details.
Just wanted to check if you have been getting this error lately (since about a week to 10 days).
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're seeing the same issue in West-Europe, and MS Support are not very helpful. We have around 3000 users spread across around 300 locations and when we see these disconnects they normally impact 70-80% of the users at approximately the same time. I would say that the odds of this being av local networking issue are pretty slim.
We same the same problem by several customers. Random users are disconnect without any reason. When this happens, event id 40 with reason code 0 appears in de eventlog.
It is happing with users with sessions from internet, but also users with a rdp shortpath connection.

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.
