No Response from GET Rest API CURL PHP Script

Hello everyone

I run this cURL PHP script on 3 different servers to get json data from another server. Here is the code:

<?php
	$consid    = "my_consid";
	$secretKey = "my_secretkey";
    date_default_timezone_set('UTC');
    $tStamp = strval(time()-strtotime('1970-01-01 00:00:00'));
    $signature = hash_hmac('sha256', $consid."&".$tStamp, $secretKey, true);
    $encodedSignature = base64_encode($signature);
    $ch = curl_init();
    $headers = array(
        'X-cons-id: '.$consid.'',
        'X-timestamp: '.$tStamp.'',
        'X-signature: '.$encodedSignature.'',
        'Content-Type: Application/JSON',          
        'Accept: Application/JSON'
    );
    curl_setopt($ch, CURLOPT_URL, "https://domain.tld/aplicaresws/rest/bed/read/xxxxxx/1/20");
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($ch, CURLOPT_TIMEOUT, 60);  
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "GET");
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_SSL_CIPHER_LIST, '[email protected]=1');
    $content = curl_exec($ch);
    $err = curl_error($ch);
    curl_close($ch);
    $data = json_decode($content,true);
    foreach ($data["response"] as $record) {}
    $data2 = array( 'data'  => $record );
    $data3 = json_encode($data2);
    $fp = fopen("bed_data.json", "w");
    fwrite($fp, $data3);
    fclose($fp);
?>
