WVD Update Error: 3000046

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


  • 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

 


  • 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.
