Can't connect to WVD client because of error meesage " no available resources"

[yatsu40]

I need help because I cant connect to WVD desktop. deploy was successful and users exist. I checked avairable users with following command, Get-RdsAppGroupUser -TenantName "xxx" -HostPoolName "xxx" -AppGroupName "Desktop Application Group". and there are two available users.

When I use both desktop app on Laptop and web browser, I failed and got error messages " you can connect because there are currently no available resources". 

Does anyone have the same problems? I'm happy if someone share the resolutions on this.

Configuration:

Active Directory : AAD DS

DN: AAD domain name is xxx.co.jp, AAD DS domain name is ooo.xxx.co.jp

The Status = no heartbeat is the issue. It's telling you that the pool cannot see the host (aka VM). This typically because there is an issues with the following post I found very help in troubleshooting and resolving:

In my case I found I was no copying/pasting the Token correctly which stuffed up the heartbeat.

Thank you Robert, Azure support announced the same answer. But it didnt work on my envilonment.

I dont know why, maybe because I re-made and deleted it with same paramaters over and over. Now I use the different host pool name and there seems to be no problems to access a new client. 

I deleted the problem host pool from management console of WVD. I will try to make the same name host pool to the problem one and access later.
