If I add an entry in /etc/hosts for the site it works. Always works from the command line. It's only from within Apache I see the issue. Multiple sites [maps.googleapis.com, fedex.com, even google.com] have the same issue. The name won't resolve without an entry in /etc/hosts.

php test.php - works
wget //hostname/test.php - fails

Actual php version is 7.0.17

				$errno,
				$errmsg,
