PHP CURL failed with Operation timeout in Kubernetes CronJob - php-curl

Question

I have a cronJob that runs at some time interval to download images from remote servers. I had alpine-php:7.2-fpm docker image. It works fine with some of the URLs. but it is failing with some URLs.
Here is the code for CURL
$fp = fopen($fileNameWithPath, 'w');
$ch = curl_init();
curl_setopt_array($ch, array(
CURLOPT_URL => $url,
CURLOPT_FILE => $fp,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_FOLLOWLOCATION => true,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "GET",
CURLOPT_CONNECTTIMEOUT => 90,
CURLOPT_TIMEOUT => 180,
CURLOPT_SSL_VERIFYHOST => 0,
CURLOPT_SSL_VERIFYPEER => 0,
CURLOPT_VERBOSE => 1
));
$result = curl_exec($ch);
$statusCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
fclose($fp);
I had enabled verbose and the logs in Kubernetes pods gives the following output
* TCP_NODELAY set

If I run this code from docker-image locally it works fine.
