After installing SSL certificate

After installing SSL certificate

Hello,
So I went through the process of installing the SSL Certificate and I finished going through the instructions. Before I did that, I also changed the port for SSL to 443. Now I'm trying to access the website for ADSelfService Plus to log in and see if the certificate is working but it will not let me to the site. It is saying this page cannot be displayed. Is there something I should be doing differently to acces the site?
Thanks
