PHP file_get_contents() returns "failed to open stream: HTTP request failed!"

Try using cURL.

<?php$curl_handle=curl_init();curl_setopt($curl_handle, CURLOPT_URL,'http://###.##.##.##/mp/get?mpsrc=http://mybucket.s3.amazonaws.com/11111.mpg&mpaction=convert format=flv');curl_setopt($curl_handle, CURLOPT_CONNECTTIMEOUT, 2);curl_setopt($curl_handle, CURLOPT_RETURNTRANSFER, 1);curl_setopt($curl_handle, CURLOPT_USERAGENT, 'Your application name');$query = curl_exec($curl_handle);curl_close($curl_handle);?>

Could this be your problem?

Note: If you're opening a URI with special characters, such as spaces, you need to encode the URI with urlencode().

<?php$lurl=get_fcontent("http://ip2.cc/?api=cname&ip=84.228.229.81");echo"cid:".$lurl[0]."<BR>";function get_fcontent( $url,  $javascript_loop = 0, $timeout = 5 ) {    $url = str_replace( "&", "&", urldecode(trim($url)) );    $cookie = tempnam ("/tmp", "CURLCOOKIE");    $ch = curl_init();    curl_setopt( $ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3) Gecko/20041001 Firefox/0.10.1" );    curl_setopt( $ch, CURLOPT_URL, $url );    curl_setopt( $ch, CURLOPT_COOKIEJAR, $cookie );    curl_setopt( $ch, CURLOPT_FOLLOWLOCATION, true );    curl_setopt( $ch, CURLOPT_ENCODING, "" );    curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );    curl_setopt( $ch, CURLOPT_AUTOREFERER, true );    curl_setopt( $ch, CURLOPT_SSL_VERIFYPEER, false );    # required for https urls    curl_setopt( $ch, CURLOPT_CONNECTTIMEOUT, $timeout );    curl_setopt( $ch, CURLOPT_TIMEOUT, $timeout );    curl_setopt( $ch, CURLOPT_MAXREDIRS, 10 );    $content = curl_exec( $ch );    $response = curl_getinfo( $ch );    curl_close ( $ch );    if ($response['http_code'] == 301 || $response['http_code'] == 302) {        ini_set("user_agent", "Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3) Gecko/20041001 Firefox/0.10.1");        if ( $headers = get_headers($response['url']) ) {            foreach( $headers as $value ) {                if ( substr( strtolower($value), 0, 9 ) == "location:" )                    return get_url( trim( substr( $value, 9, strlen($value) ) ) );            }        }    }    if (    ( preg_match("/>[[:space:]]+window\.location\.replace\('(.*)'\)/i", $content, $value) || preg_match("/>[[:space:]]+window\.location\=\"(.*)\"/i", $content, $value) ) && $javascript_loop < 5) {        return get_url( $value[1], $javascript_loop+1 );    } else {        return array( $content, $response );    }}?>
