ATP Sensor service is continuously trying to start but stops itself

Hello Techies, 

I've installed ATP Sensor across multiple DCs and it was completed successfully. However, the service is continuously trying to start and stop itself on every machine it's been installed on, with the following error message appearing in the Microsoft.Tri.Sensor-Errors log:

Error ExceptionHandler Microsoft.Tri.Infrastructure.ExtendedException: RestrictCpuAsync failed, exiting ---> System.Net.Http.HttpRequestException: An error occurred while sending the request. ---> System.Net.WebException: The request was aborted: Could not create SSL/TLS secure channel.

Has anyone came across this issue? Really appreciate any pointers here. 

Thank you!
