Can't Connect
We've been running WVD for a few months. Our users regularly (once or twice weekly) receive an error "Cannot connect no available resources". What resource does this indicate needs to be increased?...

MicrosoftI've also seen this error message when using the Scaling Automation solution. If your scaling isn't aggressive enough, users will see this message until a new session host is turned on by the Scaling Automation solution. So if you choose the default of 15 minutes, there could be 15 minute gap where users can't connect. You can test different values for the "SessionThresholdPerCPU" and "RecurrenceInterval" to try to work around this issue. For the "RecurrenceInterval", the smallest recommended value is 5 minutes and that's for small WVD deployments. Also, its worth mentioning, the SessionThresholdPerCPU value can be a decimal number.
