WVD ARM Not able to Connect with Host Pool

Copper Contributor

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 -



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


Thanks !! I am able to Fix this , Actually its known issue in Win10 2004 



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]

post that It work perfectly fine .
