This happen because selinux avoid db connections from the httpd server to the remote db server. To solve it you need to access your server trough ssh or just open a console if you have pretencial acces and do the follow:

You must check in the SELinux if the port 80 is managed in. You can check it typing # semanage port -l | grep http_port_t for list and check:

http_port_t                    tcp      443, 488, 8008, 8009, 8443, 9000

If you need to add the required port, just type:

# semanage port -a -t http_port_t -p tcp 80
