PHP CURL不获取代理（没有身份验证）

Can't obtain answer with CURL request via proxy without auth.

 $url ="https://www.website.com";
  $ch = curl_init($url);     
  curl_setopt($ch, CURLOPT_HEADER, 0);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch, CURLOPT_TIMEOUT, 20);
  curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, true);       
  curl_setopt($ch, CURLOPT_PROXY, "Proxy:Port");
  curl_setopt($ch, CURLOPT_PROXYUSERPWD,"");//no auth
  $response = curl_exec($ch);
echo "cURL time: " . (time() - $loadtime) . "s<br />\";
if ($response === false) {
    echo "cURL Error: ", curl_error($ch);
} else {
    echo $response;
}

Server answer: cURL time: 1s \ cURL Error: TCP connection reset by peer

checking connection with another way:

 $ch = curl_init(); 
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, 0);
curl_setopt($ch, CURLOPT_PROXY, 'proxy:port');
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'GET');
curl_setopt ($ch, CURLOPT_HEADER, 1);
$data = curl_exec ($ch);  
$curl_info = curl_getinfo($ch);
curl_close($ch);
echo '<br />';
print_r($curl_info);
