WVD ARM Not able to Connect with Host Pool

[Msbskbmkbcoop]

Have Created the Host Pool Published Desktop using windows 10 Market Place image , Assigned permission to users . From RD client and HTLM ( Using ARM URL )  Resources are available when click to access  got Error Please contact your Admin . We couldn't connect to Gateway Please contact your administrator .

While I publish Same image in Non ARM its working Fine .

I updated the RD Client to Latest,  ARM Deployment Log shows everything Fine , Restarted the VMs ( Session Hosts ) , Assigned users doesn't have MFA enable .

Are you using Windows 10 multi-user version 2004?

If so have a look at this post - https://techcommunity.microsoft.com/t5/windows-virtual-desktop/investigating-issue-with-windows-10-e...

We had the same issue with Windows 10 2004 Multisession. We created another hostpool with Windows 1909 Multisession and the issue went away.

Refer to this Article 

There is workaround for Win10 2004 Version We need to update the Registry key 

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\rdp-sxs]
"fReverseConnectMode"=dword:00000001
