Enable SSL for admin portal

I am new to the ServersCheck application and seeing it for the first time in a company I just joined. It looks like the admin portal is currently only logging in via HTTP. Is there a way to enable SSL and force HTTPS only so I can bind a certificate from my Internal CA? Do I need to upgrade to the latest version to get this functionality? It looks like we are on a pretty old version. 12.0.1.

You may download the new software from their website to verify.
