Nope! See that is a browser thing. Port 2087 is a port identified to WHM as secured. When you as a user login to WHM, you type , I use my IP. that is when you can get a certificate error, and choose to simply ignore it. Do you get a cert error when connecting ssh? Only browsers and FTP identify certificates. I hope I have tried to help you understand. I get confused also. If I wrong, then I stand corrected.
Code:
https://hostname.server.com:2087
