That is because of SE Linux.

To fix it:

/usr/sbin/setsebool httpd_can_network_connect true

Or you can also set the security settings,

-> Go to Security Level configurations and Change Tab to SELinux

And modify SELinux policy Check

Allow HTTPD scripts and modules to connect to the network

under HTTPD service
