php_network_getaddresses: getaddrinfo failed

Question

I am getting this error in all the functions of Image GD library.

$im = @imagecreatefromjpeg("src/bg.jpg") or die('Cannot Initialize new GD image stream');
function copyImage1($im, $dp1_name, $x1, $y1){
    $dp1 = imagecreatefromjpeg($dp1_name);
    list($w1, $h1) = getimagesize($dp1_name);
    imagecopy($im, $dp1, 35, 130, 0, 0, $w1, $h1);
}
function copyImage2($im, $dp2_name, $x2, $y2){
    $dp2 = imagecreatefromjpeg($dp2_name);
    list($w2, $h2) = getimagesize($dp2_name);
    imagecopy($im, $dp2, 618, 125, 0, 0, $w2, $h2);
}

$box = imagettfbbox(30, 0, "src/font.ttf", $user_name);
imagettftext($im, 23, 0, 53, 348, imagecolorallocate($im, 73, 184, 227), "src/font.ttf", "hello");
imagettftext($im, 23, 0, 628, 348, imagecolorallocate($im, 73, 184, 227), "src/font.ttf", "byr");
copyImage1($im, "http://graph.facebook.com/100001504336690/picture?width=153&height=143", 10, 10);
copyImage2($im, "http://graph.facebook.com/100001504336690/picture?width=138&height=158", 10, 10);

$file_name = "dump/" . rand(1000, 9999) . "-id-" . rand(1000, 9999) . ".jpg"; 
imagejpeg($im, $file_name, 80);
imagedestroy($im);


?>

The files are available at their place,

Code was working fine but now it is not working. I don't know wyy it is not working now..

Solution 1

The server that is running this code has DNS servers which it uses to resolve domain names, in this case, graph.facebook.com. It's either that those DNS servers are down or the server is misconfigured and can't reach whatever DNS servers it's supposed to use.

Solution 2

Restarting apache server also resolved my issue. I recently moved to a dedicated server so there were some initial DNS issues.
