We have a WVD deployment and we have faced some issues with WVD, here you have the list of our current pain points:
Users are getting this error messages while trying to access WVD through the Remote Desktop App or through the Web
The error message: “The task you are trying to do can’t be completed because Remote Desktop Services is currently busy” while connecting to the WVD pool”
The error message: “Oops, we couldn’t connect to “MyPC-E3” we could not connect to the gateway because of an error” while connecting to the WVD pool”
The error message: “We couldn’t connect to the Remote Desktop Gateway because of an orchestration error”
To add a little bit more on this, we have found that every time that the users are getting these errors, some of the WVD hosts in an RDP session with the local administrator account are showing a black screen and the only way to fix it is by restarting the PC.
Our current WVD host pool has 8 PCs, 4 are Windows 10 Enterprise version 1809 and 4 are Windows 10 Enterprise version 1903.
Feel free to ask any minor details that could be relevant for a solution.
