problem in using OAuth for Twitter

Question

I have implemented OAuth for twitter using Abraham Williams php library. It is working fine for me on personal web server(Apache). But when I uploaded all my application files to a public web hosting domain, it stops working. When I press the button 'sign in with twitter account' that directs user to 'connect.php' which builds twitter link to authenticate my application, it doesn't build the link. Rather control halts on that 'connect.php' page. Here is connect.php

<?php
session_start();

require_once 'twitteroauth/TwitterOAuth.php';
define("CONSUMER_KEY", "***************");
define("CONSUMER_SECRET", "********************************");

$connection = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET);
$request_token = $connection->getRequestToken('http://babar.phpnet.us/callback.php');

$_SESSION['oauth_token'] = $request_token['oauth_token'];
$_SESSION['oauth_token_secret'] =
$request_token['oauth_token_secret'];

$url = $connection->getAuthorizeURL($request_token);
header('Location: ' . $url);
?>

Here is callback.php

<?php
session_start();

require_once 'twitteroauth/TwitterOAuth.php';
define("CONSUMER_KEY", "****************");
define("CONSUMER_SECRET", "*********************************");

if (
    isset($_REQUEST['oauth_token']) 
    && $_SESSION['oauth_token'] !== $_REQUEST['oauth_token']) 
    {
     //echo 'Session expired';
     header('Location: ./connect.php');
    }
  else {
        $connection = new TwitterOAuth(CONSUMER_KEY,CONSUMER_SECRET,
        $_SESSION['oauth_token'],$_SESSION['oauth_token_secret']);
        $_SESSION['access_token'] = 
        $connection->getAccessToken($_REQUEST['oauth_verifier']);
        header('Location: index1.php');
       }
 ?>

index1.php

  if (empty($_SESSION['access_token'])) {
     header('Location: ./connect.php');
    }

     require_once 'twitteroauth/TwitterOAuth.php';
     define("CONSUMER_KEY", "**************");
     define("CONSUMER_SECRET", "*******************");

     $connection = new TwitterOAuth(CONSUMER_KEY,CONSUMER_SECRET,
     $_SESSION['access_token']['oauth_token'],
     $_SESSION['access_token']['oauth_token_secret']
    );

    include("index.php");
    $tweetmsg = $_POST['t_update'];
    $result = $connection->post('statuses/update', array('status' => $tweetmsg));
      if (200 === $connection->http_code) {
         //echo'tweet posted';
         }
       else {
             $resultmsg = 'Could not post Tweet. Error: '.$httpCode.'  
             Reason:'.$result->error; 
             //echo $resultmsg;
        }
     ?>

Same version of PHP in both locations? Check with <?php phpinfo(); ?>. PHP4 in one place and PHP5 in the other could be a problem. After that, I'd start looking at differences between included libraries: cURL, etc. ... — ebynum

Make sure the clock on the server is properly synced with NTP. If the time differers from the clocks on Twitter's servers by more then five minutes requests will fail.

You should also check to see if there is a firewall blocking https://api.twitter.com.
