Can't send the request to the server - php

Question

I've some problem with the PHP script. So, I'm trying to connect to the FMI Server, but when I'm enter a valid credentials the server always return HTTP code 330, instead of 200 OK. Also when I'm trying with invalid credentials it's return 401 and it's okay, but why I've this problem only with VALID credentials?
What I'm tried?
curl_setopt($ch,CURLOPT_ENCODING , "gzip");
But no luck :(
Here's my code:
<?php
$username = "callibra#yandex.ru"; //Valid login
$password = "callibra4App"; //Valid Password
class FMIWebApplication {
private $client = array(
"user-agent" => "FindMyiPhone/472.1 CFNetwork/711.1.12 Darwin/14.0.0",
"headers" => array(
"X-Apple-Realm-Support" => "1.0",
"X-Apple-Find-API-Ver" => "3.0",
"X-Apple-AuthScheme" => "UserIdGuest",
"X-Apple-I-MD-RINFO" => "17106176",
"Accept" => "*/*",
"Connection" => "keep-alive",
"Accept-Encoding" => "br, gzip, deflate",
"Accept-Language" => "en-us",
"X-Apple-I-TimeZone" => "GMT+2",
"X-Apple-I-Locale" => "en_US"
)
);
public $username;
public $password;
public $devices = array();
public function __construct($username, $password) {
$this->username = $username;
$this->password = $password;
$this->authenticate();
}
public function authenticate() {
$url = "https://fmipmobile.icloud.com/fmipservice/device/".$this->username."/initClient";
list($headers, $body) = $this->curlPOST($url, "", $this->username.":".$this->password);
/*
if ($headers["http_code"] == 200) {
return 200;
};
if ($headers["http_code"] == 401) {
return 401;
};
if ($headers["http_code"] == 403) {
return 403;
};*/
echo $headers["http_code"];
}
private function curlPOST($url, $body, $authentication = "") {
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $body);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_USERAGENT, $this->client["user-agent"]);
curl_setopt($ch, CURLOPT_SSLVERSION, 6);
if (strlen($authentication) > 0) {
curl_setopt($ch, CURLOPT_USERPWD, $authentication);
}
$arrHeaders = array();
$arrHeaders["Content-Length"] = strlen($request);
foreach ($this->client["headers"] as $key=>$value) {
array_push($arrHeaders, $key.": ".$value);
}
curl_setopt($ch, CURLOPT_HTTPHEADER, $arrHeaders);
$response = curl_exec($ch);
$info = curl_getinfo($ch);
$header_size = curl_getinfo($ch, CURLINFO_HEADER_SIZE);
$responseBody = substr($response, $header_size);
$headers = array();
foreach (explode("\r\n", substr($response, 0, $header_size)) as $i => $line) {
if ($i === 0)
$headers['http_code'] = $info["http_code"];
else {
list ($key, $value) = explode(': ', $line);
if (strlen($key) > 0)
$headers[$key] = $value;
}
}
return array($headers, json_decode($responseBody, true));
}
}
$API = new FMIWebApplication($username, $password);
$API->authenticate();
?>
That's what I'm getting from the server:
