Sensor failed to register due to connectivity issues

[mb571]

Hello Microsoft Community

We are getting the error pop up when running through the installer - it pops up after entering the key

"The Sensor failed to register due to connectivity issues"

From the log file - one line pops out:

at Microsoft.Tri.Sensor.Deployment.Bundle.UI.DeploymentModel.<ValidateCreateSensorAsync>d__52.MoveNext() failed connecting to service. The issue can be caused by a transparent proxy
