我已经开发了一个Laravel框架的Web服务，该框架使用guzzle/guzzle包来创建令牌，并且在主机上运行良好。由于我已将Web服务从主机移至CentOS服务器，因此它无法返回令牌。这是我创建令牌的代码：
$client = new GuzzleClient();
$response = $client->request('POST', env('APP_URL') . '/oauth/token', [
RequestOptions::JSON => [
"username" => $username,
"password" => $password,
"grant_type" => "password",
"client_id" => 3,
"client_secret" => "iUwyfTzdf37JPJ6qYGDegmUWbYmZl3a6YGxywrud",
"theNewProvider" => "subscribers"
]
]);
return $response;
当我使用Postman调用Web服务时，这是响应：
Could not get any response
There was an error connecting to http://x.x:x/api/authenticate.
Why this might have happened:
The server couldn't send a response:
Ensure that the backend is working properly
Self-signed SSL certificates are being blocked:
Fix this by turning off 'SSL certificate verification' in Settings > General
Proxy configured incorrectly
Ensure that proxy is configured correctly in Settings > Proxy
Request timeout:
Change request timeout in Settings > General
然后我按照Postman的配置进行配置，但是没有任何变化。我不知道原因。
当我打印响应时，如下：

我使用CURL检查我的Web服务响应，但出现以下错误：
curl error 56 illegal or missing hexadecimal sequence in chunked-encoding
