`curl`が機能せず、メッセージも表示されません。

アドレスを確認するためにカールを使用するスクリプトがありますが、なぜ以下のようないくつかのアドレスで停止するのですか？それを防ぐにはどうすればよいですか？詳しくはこのアドレスを確認してください

curl https://10.10.34.36/test

私のスクリプト：

$sites = file_get_contents('./sites.json');
$sites = json_decode($sites);

    curl_setopt($ch, CURLOPT_NOBODY, 1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 1); 
    
// The maximum number of seconds to allow cURL functions to execute.
    curl_setopt($ch, CURLOPT_TIMEOUT, 8); //timeout in seconds
    $headers = curl_exec($ch);
    curl_close($ch);

    $result = array("old"=>$url);
    // Check if there's a Location: header (redirect)
    if (preg_match('/^Location: (.+)$/im', $headers, $matches)){
        $result["new"] = trim($matches[1]); 
        $html = file_get_contents($result["new"]);

    return "";
