Client connection error of RDGateway: ConnectionFailedClientDisconnect (-2147467259)

[bacharbader]

Some users disconnect from AVD session with this error:

Kind	Source	Error	Message sample
Deployment	RDGateway	ConnectionFailedClientDisconnect (-2147467259)	The network connection between the Windows Virtual Desktop client and the service was unexpectedly interrupted.

How can I know the main reason of this disconnection ?

I have solved this issue by asking the user to install the latest updates for remote desktop application.

@bacharbader 
Found this blog. We're encountering the same issue; all our client is at the most recent AVD Client Version. 
ConnectionFailedClientDisconnect (-2147467259)

Currently working through various scenarios to try and figure this one out.
Almost 1/3 of our daily users gets this error - 550 according to AVD Insights.

We'll be logging a MS Support Case.

Seeing this as well, I was having a ton of the UDP Shortpath errors, but after using the ADMX template for AVD I was able to resolve that, now Im still seeing a lot of this.

Did you happen to get anything out of Microsoft about that error "ConnectionFailedClientDisconnect (-2147467259)" ?? Our users are on the current version of the RDClient

Anyone was able to solve this issue? Im having random disconnects even with updated RDP APP. Same exact error message. I have a Microsoft Support ticket open for 2 months so far and they do not help at all. We are alone basically to solve Microsoft Product problems.

@bacharbader 

Make sure latest version, isolate endpoint and redeploy client, this is my suggestion in past experience

I also have the same thing here.
what firewall do you have for the AVD hosts ?

[#8]

No reply from Microsoft support.

@BacharBader77 I resolved this by using the AVD ADMX template and forced the hosts to use TCP instead of UDP streams.

Our hosts are behind an Azure firewall.
