Sbarnet: Thank you for sharing the logs. Unfortunately there isn't enough information to debug the disconnects. I recommend to open a support case and provide activity IDs for the connections you see issues with.

We are still seeing disconnects at every morning at 08:06 CET time for Azure Virtual Desktop.

- 1,5 years after first reported.

- Multiple RDAgent + RD Client updates, none has fixed it

- Troubleshooted all Intune clients and AVD Session hosts

- Troubleshooted firewall and URL check, no specific denies

- Tried new images, clean marketplace images

- Tried clean OUs with GPO inheritance disabled

- RDP Shortpath enabled

- Accelerated Networking enabled

- Works fine throughout the day except these static disconnects in morning, so shouldn't be firewall.

- The whole nature of the disconnects is very "scheduled task"-ish. We just cannot find any tasks at these times. Either that or network packets are dropped at this time for some reason. I really wish there was more documentation explaining the EventViewer logs for Azure Virtual Desktop session hosts.

Around 4 MS Support cases.

Currently we are awaiting MS support saying network is analyzing traces etc.

This is the log we see in event viewer when it happens:
