Remote Desktop not working in Admin Center

Setup a test of the Windows Admin Center, the only thing I cant seem to get to work is the Remote Desktop tab. I just get the spinning dots and errors in the console, which I have attached. Any Ideas...

    I could fix this problem by enabling "Allow users to connect remotely by using Remote Desktop Services" policy settings (gpedit.msc or gpo). This policy add fDenyConnection=0 value to "HKLM\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services", so $resgistryKey never set to null.

Perhaps it is only necessary for something to exist in the "HKLM\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services" key. If there is no value in this reg path, $regisgtryKey vaiable (you can see it by using [>_] show power shell script button) set to null, and followed script will cause error.

$registryKey = Get-ItemProperty -Path $RdpGroupPolicyRegistryKey -ErrorAction SilentlyContinue

if ((Get-Member -ImputObject $registryKey ... <- Error

I can confirm that setting either of these works. It is not necessary to add both:

 

REG ADD "HKLM\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services" /v "KeepAliveEnable" /t REG_DWORD /d 1 /f


REG ADD "HKLM\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services" /v "KeepAliveInterval" /t REG_DWORD /d 1 /f

    Exactly. It is important that there is at least one value in this place. The name, type, and data of that value can be anything.

     

    This bug was probably fixed in Windows Admin Center 1809.5 Insider Preview.

      I'm still unable to remote desktop via Admin Center even after making the changes in the registry:

      REG ADD "HKLM\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services" /v "KeepAliveEnable" /t REG_DWORD /d 1 /f
      REG ADD "HKLM\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services" /v "KeepAliveInterval" /t REG_DWORD /d 1 /f

      I'm receiving the following error:
      HTTP400: BAD REQUEST - The request could not be processed by the server due to invalid syntax. (XHR)PUT - https://[gatewayserver:8080]/api/nodes/[servername]/features/powershellApi/pssessions/instantSession

      I installed version 1809 on a new 2016 vm that has nothing else installed on it. Any assistance would be greatly appreciated.

        I updated to 1809.5 which resolved my issue.
