- User Assignment - Ensure users are assigned to the Application Group (Desktop/RemoteApp).
- Session Host Health - Verify session hosts are Available (not “Unavailable” / “Shutdown”).
- AVD Agent Status - Check if AVD Agent + Bootloader are up to date (outdated agent can block logins).
- User Sign-in Test - Try login via AVD Web Client (to isolate client-side issues)
- Recent Changes
- Check if any of these were recently enabled:
- GPOs (e.g., watermark / graphics)
- Windows Updates / patches → Known cases show connection failures after updates or GPU-related settings.
- RBAC / Access
- Confirm users have proper roles:
-
Virtual Machine User Login -
Desktop Virtualization User
- Network / DNS - Ensure session hosts can reach AVD endpoints (no firewall/proxy block).

start with host pool health + user assignment + AVD agent status but I think we need more details & for AVD “VM is up but users cant connect” check the session hosts must be available, not Unavailable or in Drain mode, AVD agent and bootloader services must be healthy, host pool registration token should not be expired, users must be assigned to the application group & the workspace must be associated with that app group.
look at azure service health for avd in that region, coz if all users suddenly fail, it may be platform side. On each session host, restart
RDAgentBootLoaderandRemote Desktop Services, loo at event viewer under avd agent logs. If hosts show unavailable, reinstall update the AVD agent. If hosts are available but only users fail, check RBAC/app group assignment and Conditional Access MFArgds,Alex

If my answer was helpful pls mark it and additional thx if u follow me at Q&A portal
