PhP的sdk如何解决API域名解析失败的问题？

如题，最近我通过PhP后台向LeanCloud中存储数据的时候，发现频繁出现调用失败。log如下：

Save object fail!exception 'RuntimeException' with message 'CURL connection (https://api.leancloud.cn/1.1/batch) error: 7 Failed to connect to api.leancloud.cn port 443: Connection timed out' in /home/wwwroot/api.ldstark.com/bigbang/payment/vendor/LeanCloud/Client.php:409
Stack trace:
#0 /home/wwwroot/api.ldstark.com/bigbang/payment/vendor/LeanCloud/Client.php(456): LeanCloud\Client::request('POST', '/batch', Array, NULL, Array, NULL)
#1 /home/wwwroot/api.ldstark.com/bigbang/payment/vendor/LeanCloud/Client.php(508): LeanCloud\Client::post('/batch', Array, NULL, Array, NULL)
#2 /home/wwwroot/api.ldstark.com/bigbang/payment/vendor/LeanCloud/Object.php(749): LeanCloud\Client::batch(Array, NULL)
#3 /home/wwwroot/api.ldstark.com/bigbang/payment/vendor/LeanCloud/Object.php(697): LeanCloud\Object::batchSave(Array)
#4 /home/wwwroot/api.ldstark.com/bigbang/payment/vendor/LeanCloud/Object.php(444): LeanCloud\Object::saveAll(Array)

我对PHP不是很熟，不清楚是不是《LeanCloud 华北节点 API 域名近日出现间歇性解析失败的说明》里说到的问题，如果是的话，请问如何在继续使用PHPSDK的情况下解决问题，因为我发现PHPSDK已经很久没更新了

如果不是这个问题的话，能不能告诉我如何解决这个问题呢？

ps：我后台是使用的阿里云的服务器跟LeanCloud通信的

就是把客户端传上来的数据处理以后，调用PHPSDK保存到LeanCloud，代码如下：

$wePayPaymentObject = new Object("WePayPayment");
foreach($objectForLeanCloud as $key => $value){
if(!is_numeric($key)){
$wePayPaymentObject->set("$key", "$value");
}
}
$acl = new ACL();
$acl->setReadAccess($objectForLeanCloud["userId"],true);
$acl->setPublicReadAccess(false);
$wePayPaymentObject->setAcl($acl);
try {
$wePayPaymentObject->save();
echo "Save object success!";
} catch (Exception $ex) {
echo "Save object fail!";
echo $ex;
}

就save()的时候会报上面的错误
