MDI Sensor failing to install on ADCS Server

Hello,

I am trying to install a MDI Sensor on an ADCS server. This server has all outbound internet access blocked. I created an outbound rule for Azure Advanced Threat Protection to allow the MDI Sensor.

Is this correct?

These are the errors I am getting when installing a MDI Sensor on an ADCS server.

Can anyone help me why the sensor is failing to install?
