我被困住了，需要有人指出我正确的方向。

在 localhost 上运行良好，但是当我推送到我们数据中心的站点的测试版本（使用沙盒设置）时失败。我正在为 c# 使用 SDK 版本 2.1.96。有任何想法吗？

谢谢

端点是：https ://api-3t.sandbox.paypal.com/2.0/

当我尝试在数据中心服务器上进行测试时，我得到：

System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: 
A connection attempt failed because the connected party did not properly respond after a period of time, 
or established connection failed because connected host has failed to respond 173.0.82.83:443

   at PayPal.PayPalAPIInterfaceService.PayPalAPIInterfaceServiceService.SetExpressCheckout(SetExpressCheckoutReq setExpressCheckoutReq, String apiUserName)
   at PayPalSetCheckoutModel.SetExpressCheckoutPP() in PayPal\PayPalCheckoutModel.cs:line 301

相关的相关代码是（直接来自 SDK 中的示例）： // 调用 API

SetExpressCheckoutReq wrapper = new SetExpressCheckoutReq();
wrapper.SetExpressCheckoutRequest = checkoutRequest;
PayPalAPIInterfaceServiceService service = new PayPalAPIInterfaceServiceService();
SetExpressCheckoutResponseType setECResponse = service.SetExpressCheckout(wrapper);

要发送的请求（来自我的本地主机）如下所示：

看起来这可能是防火墙问题。

我会检查您是否可以在数据中心机器的浏览器中查看https://api-3t.sandbox.paypal.com/2.0/并获得与从笔记本电脑相同的输出。接下来要检查的是端口 443 是否可用作数据中心机器的路由。
