HTTPS Connection for Selenium Grid Hub

The documentation states to use http://%s:%s@hub.crossbrowsertesting.com:80/wd/hub for the selenium grid hub address https://support.smartbear.com/crossbrowsertesting/docs/automated-testing/frameworks/selenium/java.html. 

How do we use HTTPS for the hub address? When I tried changing the hub address to use HTTPS, I received errors regarding the hub connection.

org.openqa.selenium.SessionNotCreatedException: 
Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.
