it took about an hour to I realized that why a fresh server which I just installed cpanel on it wont response on port 80 and ssl but ssh works! at the first look it shouldn’t be iptables because I was able to connect through ssh so I tried to search everywhere in this damn server, the last try was to stopping iptables without any hope and thankfully it worked. Ok anyway I couldn’t leave iptables stopped so here we need a flush!
# iptables –flush
