SSL Problem

I purchased an SSL Certificate, and issued it to my server's hostname. This is because I use the following two URLs for CentOS WebPanel:
https://my.hostname.com:2083
https://my.hostname.com:2087

I can't get SSL to work on either of these - chrome tells me it can't trust it blah blah blah, however, when I got to the following URL:
https://my.hostname.com

It works just fine here. How can I get my SSL Certificate to work on CentOS WebPanel?

You don't actually need to purchase a certificate for your CWP.
1. Just simply change your hostname (Server settings>Change hostname)
2. Make sure your hostname in CWP must be matched with your actual hostname of your server (to verify , login SSH and type hostname), or you can do simple check:
nano /etc/hosts
3. reboot

To access your secured CWP:  https://YOUR_SERVER_IP:2013
