无法通过 pushsharp 中的 tcp 客户端连接到 feedback.sandbox.apple.com答案

【问题标题】：Unable to connect to feedback.sandbox.apple.com via tcp client in pushsharp无法通过 pushsharp 中的 tcp 客户端连接到 feedback.sandbox.apple.com
【发布时间】：2015-09-08 11:18:58
【问题描述】：

无法使用端口号 2196 连接到 feedback.sandbox.push.apple.com。使用 TCP/SSL 在 windows 防火墙中打开端口（5223、2915、2916、443）。

也尝试通过 telnet 连接，但没有帮助。

得到以下异常

Service Exception: PushSharp.Apple.ApplePushService -> System.Net.Sockets.Socket

另外，连接沙盒不需要证书，为什么会出现这个异常？

【解决方案1】：

您确实需要来自 Apple 开发者门户的开发证书才能连接到沙盒。但是不知道你是否需要用它来连接feedback.sandbox.apple。

我似乎无法找到关于反馈服务是否仍然有效的直接答案。我认为 APNS 反馈服务现在已被弃用。这可能就是您收到此错误的原因。

Does APNS Feedback service no longer exist as per new APIs?

APNS Feedback Service - is it still alive?
