VM Connection very often gets disconnected
Hello! I'm seeing a lot of disconnects in my hostpools. Just in the last 24 hours, a user had the following The connection from the client to the Windows Virtual Desktop service was terminated u...
That is interesting. Usually, you'll see the packet loss on TCP as the screen locks up, with scrolling draws of the screen as the TCP session retransmits or naggles and adjust the sliding window around.
It must be that shortpath just is not prime time ready, the UDP packet loss is enough to kill the connection on the Azure end but not bad enough to notice in TCP or something else. Like everyone in this thread, I go for periods where I have 0 issues. Then the disconnects pile on. Sadly, I need shortpath/UDP to be working as I tried pure TCP and the session latency wasn't working well for my end users. I've actually thought about bringing it back in house.

Do you use a NAT Gateway for the subnet?
- Out of curiosity, have you found issues when using a NAT Gateway?
We have disabled RDP Shortpath completely and switched back to TCP for stability and aid reconnect however we experience this issue as well for a fair few users everyday so we are keen to get to the bottom of this.
- I doubt we will anytime soon. I did the same thing on disabling and have had huge improvements. But it's still have occasional disconnects. Way less stable compared to the days of running this stuff in my own datacenter.
My next issue is I have to run all my clients on 1.2.4337.0 of the Remote Desktop client. As any newer version has started to have video issues where it draws windows as black boxes or it warps the image. 1.2.4337.0 Doesn't have any issues at all. I have tried disabling all the video acceleration and changing compression algorithms with the newer versions and nothing works. It only happens to remoteapps and not the full desktop as well.
I submitted a case about it a month ago and I have yet to have anyone take the case to look at it or let me know they are already tracking it as a bug. Hence why I doubt we will see this issue anytime soon. Azure doesn't care, hence why they outsource support and the break fix support teams are tiny. I'm getting ready to pull the trigger to bring this back in house. Microsoft has built a house of cards I think.
Jason_1995 Nope, I currently use Azure VWAN with a secured hub in a hub spoke architecture.
