为什么PHP CURL函数在Tor v3.onion域上返回CURLE_COULDNT_CONNECT

Recently I found php curl can't get info from Tor V3.onoin. When I try to curl v3 domain it return CURLE_COULDNT_CONNECT. My method is ok on v2. Here's an domain example. v3 domain:http://vww6ybal4bd7szmgncyruucpgfkqahzddi37ktceo3ah7ngmcopnpyyd.onion/ v2 domain:http://torbox3uiot6wchz.onion/

Here's my code.

<?php
function get_content($url, $cookie)
{
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
    curl_setopt($ch, CURLOPT_USERAGENT, $GLOBALS ['user_agent']);
    curl_setopt($ch, CURLOPT_PROXY, "http://127.0.0.1:9150/");
    curl_setopt($ch, CURLOPT_PROXYTYPE, 7);
    $return = curl_exec($ch);
    $errno = curl_errno($ch);
    $info = curl_getinfo($ch);
    $info['errno'] = $errno;
    $log = json_encode($info);
    putLog($log);
    curl_close($ch);
    return $return;
}

function putLog($log)
{
    $log .= "nn";
    $logDir = dirname(__FILE__);
    $logPath = $logDir . "/curl_log.txt";
    if (!file_exists($logPath)) {
        $handle = fopen($logPath, 'w');
        fclose($handle);
    }
    file_put_contents($logPath, $log, FILE_APPEND);
}

$cookie = dirname(__FILE__) . '/cookie_ydma.txt';
$output_first = get_content("http://torbox3uiot6wchz.onion/", $cookie);
echo $output_first;

?>
