Preview Website

The problem with my Virtualmin is following, I am in the middle of a migration from CentOS 6 to
CentOS 7. So the first domain i brought over luckily I got it to show up in the CentOS 7 Virtualmin, however when I click Preview Website then it displays me the following:

“Failed to connect to : Connection refused”

So I figured maybe the ports were disabled. However they weren’t.

Perhaps someone smarter then me can suggest what could possibly be wrong?

the problem may be a fault in Apache
