Centos 7 (1611) - access problems with http

[SystemadminEU]

My problem is that I cannot get http, to work outside the server itself.

I installed wordpress, and downloaded the MySQL database, phpmyadmin, and created internal/external DNS.
I can browse to the word-press login site and login, no problem, as long as it is on the server itself.

The problems
1. The external access to the wordpress site is just not working. I am using apache 2.4.6.
2. Nor can I Putty/WinSCP to the server. (Firewall is disabled)

Where do I locate what I need to change?

If you cannot ssh to the machine then something is amiss either with your firewall or your routing.

I disabled the firewall, but the installation is now fubar, and I have reinstalled a new one.

Now I can ssh and scp into the new installation.
It seems that errors might be consistent when writting new files.
