On 02/12/2021, We got hit by the following error while connecting to the WVD after a restart.
Error: We couldn’t connect because there are currently no available resources. Try again later or contact tech support for help if this keep happening.
Resolution:
When we check the status of the session host, it was unavailable.
Get-RdsSessionHost -TenantName <tenant name> -HostPoolName <host pool name>
- Logged in to the WVD VM as an admin.
- We found that RDP Client was recently updated on the WVD.
-
We removed old client for the following
- Remote Desktop Agent Boot Loader
- Remote Desktop Services Infrastructure Agent
- Remote Desktop Services Infrastructure Geneva Agent
- Remote Desktop Services SxS Network tack
- Remote Desktop Agent Boot Loader
- Login to WVD PowerShell and remove the RDSH from host pool
Remove-RdsSessionHost -TenantName <tenant name> -HostPoolName <host pool name> -Name <session host name> -Force
-
Create Registration Token: New-RdsRegistrationInfo -TenantName tenant name> -HostPoolName <host pool name> -ExpirationHours <token expiration in hours> | Select-Object -ExpandProperty Token > <path>
-
Downloaded the new versions from the following links.
- Ran the WVD Agent and provided the exported key. Completed the installation
- Ran the WVD Bootloader
-
Ran the following command to check the RDSSessionHost status but it was still unavailable.
Get-RdsSessionHost -TenantName <tenant name> -HostPoolName <host pool name>
-
Checked the certificate for my local computer, and found multiple certificates. We deleted old certificates.
- Then reinstalled WVD Agent and WVD Bootloader
- Restarted the WVD VM
-
Issue resolved. Now RDSSessionHost was available
Conclusion:
Microsoft push new certificates and it caused the issue. We removed the certificate and issues resolved. Microsoft support accepted this was Microsoft fault.
