PayPalHttpConnection.php第174行中的PayPalConnectionException：

嘿，我正在开发Laravel 5.3，我正在尝试实现PayPal Api，我在网上找到了一个教程，所以我遵循了每一个步骤，但后来我遇到了一个错误，我不知道如何解决它

这是我得到错误的代码：

try{
        $payment->create($this->_apiContext);
    } catch (\PayPal\Exception\PayPalConnectionException $ex){
        if(\Config::get('app.debug')){
            echo 'Exception: ' . $ex->getMessage() . PHP_EOL;
            $err_data = json_decode($ex->getData(), true);
            echo $err_data;/*
            echo $ex->getCode();
            echo $ex->getData();*/
            exit;
        } else {
            die('Ups! Algo salio mal');
        }
    }

这就是错误：
