Nest Rest API连接被拒绝

我正试图使用REST方法将我的家庭模式设置为外出模式。我正在用cURL尝试，但我一直收到一个"重定向后连接被拒绝"的消息。

我的代码：

$ch = curl_init("https://developer-api.nest.com/structures/$id?auth=$access_token");
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT"); 
curl_setopt($ch, CURLOPT_POSTFIELDS, '{"away":"away"}');
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_STDERR, $fp);
curl_setopt($ch, CURLOPT_PUT, true);
echo curl_exec($ch);

错误日志（更改了我的id和访问代码）：

你知道为什么最初的连接会起作用，但重定向不起作用吗？
