PHP curl返回（35）：SSL连接错误

Question

Im trying to visit the following page using php curl 7.35.0 using the following code:

    $this->ch = curl_init();
    curl_setopt($this->ch, CURLOPT_CONNECTTIMEOUT, 3000);
    curl_setopt($this->ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/37.0.2062.120 Safari/537.36");
    curl_setopt($this->ch, CURLOPT_SSL_VERIFYPEER, true);
    curl_setopt($this->ch, CURLOPT_FOLLOWLOCATION, TRUE);
    curl_setopt($this->ch, CURLOPT_HTTPHEADER, array('Content-Type: application/x-www-form-urlencoded'));
    curl_setopt($this->ch, CURLOPT_TIMEOUT, 3600);
    curl_setopt($this->ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($this->ch, CURLOPT_URL, 'https://asp.reflexion.net/login');
    curl_setopt($this->ch, CURLOPT_RETURNTRANSFER, 1);
    $content  = curl_exec($this->ch);
    $httpCode = curl_getinfo($this->ch, CURLINFO_HTTP_CODE);
    if ($errno    = curl_errno($this->ch))
    {
        $error_message = curl_strerror($errno);
        echo "cURL error ({$errno}):
 {$error_message}";
    }
    echo "<br>";
    echo "http code: " . $httpCode . "<br>";
    echo "content: " . $content;

Which returns the following:

cURL error (35): SSL connect error

http code: 0 content:

Did anyone run into this problem before?
