Curl error: Operation timed out

Some time this error in Joomla appear because some thing incorrect with SESSION or coockie. That may because incorrect HTTPd server setting or because some before CURL or Server http requests

so PHP code like:

  curl_setopt($ch, CURLOPT_URL, $url_page);
  curl_setopt($ch, CURLOPT_HEADER, 1);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
  curl_setopt($ch, CURLOPT_TIMEOUT, 30); 
  curl_setopt($ch, CURLOPT_COOKIESESSION, TRUE);
  curl_setopt($ch, CURLOPT_REFERER, $url_page);
  curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
  curl_setopt($ch, CURLOPT_COOKIEFILE, dirname(__FILE__) . "./cookie.txt");
  curl_setopt($ch, CURLOPT_COOKIEJAR, dirname(__FILE__) . "./cookie.txt");
  curl_setopt($ch, CURLOPT_COOKIE, session_name() . '=' . session_id());

  curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
  if( $sc != "" ) curl_setopt($ch, CURLOPT_COOKIE, $sc);

will need replace to PHP code

  curl_setopt($ch, CURLOPT_URL, $url_page);
  curl_setopt($ch, CURLOPT_HEADER, 1);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
  curl_setopt($ch, CURLOPT_TIMEOUT, 30); 
//curl_setopt($ch, CURLOPT_COOKIESESSION, TRUE);
  curl_setopt($ch, CURLOPT_REFERER, $url_page);
  curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
//curl_setopt($ch, CURLOPT_COOKIEFILE, dirname(__FILE__) . "./cookie.txt");
//curl_setopt($ch, CURLOPT_COOKIEJAR, dirname(__FILE__) . "./cookie.txt");
//curl_setopt($ch, CURLOPT_COOKIE, session_name() . '=' . session_id());

    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false); // !!!!!!!!!!!!!
  //if( $sc != "" ) curl_setopt($ch, CURLOPT_COOKIE, $sc);

May be some body reply how this options connected with "Curl error: Operation timed out after .."

Your curl gets timed out. Probably the url you are trying that requires more that 30 seconds.

If you are running the script through browser, then set the set_time_limit to zero for infinite seconds.

set_time_limit(0);

Increase the curl's operation time limit using this option CURLOPT_TIMEOUT

curl_setopt($ch, CURLOPT_TIMEOUT,500); // 500 seconds

It can also happen for infinite redirection from the server. To halt this try to run the script with follow location disabled.

curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false);

I got same problem lot of time. Check your request url, if you are requesting on local server like 127.1.1/api or 192.168...., try to change it, make sure you are hitting cloud.
