我要疯狂使用Apple推送通知！ 我开发了我的应用程序和测试通知后，Ray Wanderlich教程和一切工作正常，直到我改变文件.pem与分配之一，并将连接字符串从gateway.sandbox.push-apple.com更改为gateway.push苹果。 COM。无法连接到ssl：//gateway.push.apple.com：2195（连接超时）
现在，如果我尝试发送邮件服务器返回
Warning: stream_socket_client() [function.stream-socket-client]: unable to connect to ssl://gateway.push.apple.com:2195 (Connection timed out)
Failed to connect: 110 Connection timed out
php文件和.pem文件是在TMDHosting：我试着问他们，如果端口号2195被关闭，因为谷歌搜索，我发现错误意味着端口被关闭。
虽然，我不明白错误是否链接到证书或服务器。
的奇怪的事情是，如果我遵循的程序与终端测试.pem文件，一切似乎工作

这让我认为这不是一个问题。质子交换膜...
我错了吗？
我已经阅读了所有类似的问题，并尝试将端口号从2195更改为30，但没有任何更改。 提示？
编辑：我发现that，似乎等于我的问题：TMDHosting告诉我
...you are located under a shared hosting environment and opening a port for you will be not possible. However note that the address to which you are making a connection on port 2195 is not associate with our server. In other words you are trying to make a connection to a remote server on port 2195. In order to make this connection to the port specified above you should make sure that the port is opened for incoming connections on the remote server and not on the server on which your account with us relies.
我需要一个VPS？
EDIT2：
在本教程中我跟着我发现
.. you will need a server that is connected to the internet. Push notifications are always sent by a server. For development you can use your Mac as the server (which we’ll do in this tutorial) but for production use, you need at least something like a VPS (Virtual Private Server). A cheap shared hosting account is not good enough. You need to be able to run a background process on the server, install an SSL certificate, and be able to make outgoing TLS connections on certain ports. Most shared hosting providers do not let you do this, although they might if you ask. However, I really recommend using a VPS host such as Linode.
最后我觉得我确实需要一个VPS。你能确定吗？ 但是，为什么如果我发送推送通知与沙箱服务器它没有VPS正常工作？
最后更新：（希望能帮助别人）好像有一个错误，因为正确的事情是，我不能发送推送通知没有沙箱，也不从我的主机生产服务器（TMDHosting ）：我的共享主机没有打开2195端口。改变提供者：一切正常。
最后，你用什么提供商？，我有同样的问题:( – 2014-10-15 10:19:32
