Problem solved, type:

/usr/sbin/setsebool httpd_can_network_connect=1

By default, SELinux does not allow Apache to make socket connections. More information can be found here.

Is this setting permanent? Or should it be added to a boot init script? Or etc file? – rolandow May 30 '13 at 08:14
Thanks a ton for this question- answer. Hours saved! It might solve one more error I got while I was trying to run a c++ executable which also tried to open ports as well. – Harsh Agrawal Jun 21 '13 at 02:39

To be keep the config across reboots use `-P` flag: `setsebool -P httpd_can_network_connect 1` – Mircea Vutcovici Jan 06 '14 at 16:25
