无法连接到graph.facebook.com端口443：连接被拒绝

Question

我是FB图形API的新手，我尝试在我的网站中包含FB登录，我遵循他们网站的官方FB登录教程，但登录后我得到以下错误：

Failed to connect to graph.facebook.com port 443: Connection refused 

的login.php

<?php 
session_start(); 
require_once __DIR__ . '/fbsdk/src/Facebook/autoload.php'; 

$fb = new Facebook\Facebook([ 
'app_id' => 'xxx', 
'app_secret' => 'xxx', 
'default_graph_version' => 'v2.3', 
// . . . 
]); 

$helper = $fb->getRedirectLoginHelper(); 
$permissions = ['public_profile', 'email']; // optional 
$loginUrl = $helper->getLoginUrl('http://-myserver-/login-callback.php', $permissions); 

echo '<a href="' . $loginUrl . '">Log in with Facebook!</a>'; 
?> 

登录-callback.php

<?php 
session_start(); 
require_once __DIR__ . '/fbsdk/src/Facebook/autoload.php'; 

$fb = new Facebook\Facebook([ 
'app_id' => 'xxx', 
'app_secret' => 'xxx', 
'default_graph_version' => 'v2.3', 
// . . . 
]); 



$helper = $fb->getRedirectLoginHelper(); 
try { 
$accessToken = $helper->getAccessToken(); 
} catch(Facebook\Exceptions\FacebookResponseException $e) { 
// When Graph returns an error 
echo 'Graph returned an error: ' . $e->getMessage(); 
exit; 
} catch(Facebook\Exceptions\FacebookSDKException $e) { 
// When validation fails or other local issues 
echo 'Facebook SDK returned an error: ' . $e->getMessage(); 
exit; 
} 

if (isset($accessToken)) { 
// Logged in! 
$_SESSION['facebook_access_token'] = (string) $accessToken; 

// Now you can redirect to another page and use the 
// access token from $_SESSION['facebook_access_token'] 
} 
?> 

例如，帆布app.php

<?php 
session_start(); 
require_once __DIR__ . '/fbsdk/src/Facebook/autoload.php'; 

$fb = new Facebook\Facebook([ 
'app_id' => 'xxx', 
'app_secret' => 'xxx', 
'default_graph_version' => 'v2.3', 
// . . . 
]); 



$helper = $fb->getCanvasHelper(); 
try { 
$accessToken = $helper->getAccessToken(); 
} catch(Facebook\Exceptions\FacebookResponseException $e) { 
// When Graph returns an error 
echo 'Graph returned an error: ' . $e->getMessage(); 
exit; 
} catch(Facebook\Exceptions\FacebookSDKException $e) { 
// When validation fails or other local issues 
echo 'Facebook SDK returned an error: ' . $e->getMessage(); 
exit; 
} 

if (isset($accessToken)) { 
// Logged in. 
} 
?> 

我已经搜查堆栈和谷歌，但我无法找到任何解决方案
