Hello,

The DNS has propagated without issue:

$ dig +short hdciyiz.com
80.240.137.7
$ curl -Ik hdciyiz.com
curl: (7) Failed connect to hdciyiz.com:80; Connection refused

The issue appears to be that Port 80 is closed on your server:

$ nmap -p80 hdciyiz.com

Starting Nmap 6.46 ( http://nmap.org ) at 2014-07-09 16:27 CDT
Nmap scan report for hdciyiz.com (80.240.137.7)
Host is up (0.17s latency).
rDNS record for 80.240.137.7: server.trfragman.net
PORT STATE SERVICE
80/tcp closed http

Nmap done: 1 IP address (1 host up) scanned in 2.54 seconds

This indicates, either, that the firewall needs to be configured to allow traffic on port 80, or that the webserver is not currently running. I recommend verifying that you webserver is running on the server.
