ConnectionFailedNoHealthyRdshAvailable
Hi,
I'm setting up a Windows Virtual Desktop env but keep hitting an error when connecting to the machine in my host pool. The error is:

The only thing different from previous deployments was a default Network Security Group on the domain services and that I've deployed using an ARM template. I've added an allow all rule on the inbound and outbound NSG but didn't change anything. The ARM deployment completed successfully.
I can RDP to the machine using a wan ip attached to the machine and can see the machine is properly domain joined.
What else can I check? Any suggestions?

Could it be that deploying the VMs to west europe is the problem as the management solution and data for these VMs will reside in the United States (US East 2 region) and optimal performance of network isn't met?

JacekM : Does the host pool still exist in that tenant? I'm not seeing anything on the backend.
- JacekMCopper ContributorNo, I' ve deleted everything for now. Deploying to west US 2 and will check if arm templates will work there out of the box.

Hi Christian,
I've setup everything from scratch, again, I can see heartbeats but can't connect to my main pool. The domain I've used is wvdpowel.onmicrosoft.com and created Tenant WVDPowel. I have the same error as previously: "We couldn't connect because there are currently no available resources. Try again later or contact tech support for help if this keeps happening".

JacekM : Thanks for redeploying. Which OS version are you running? If you run Get-RdsSessionHost for your host pool, it mentions that the side-by-side stack listener is not ready, so I'd like to try tracking down the steps you've done and what OS you're running this with.
