GCM连接错误 [英] GCM connection error

问题描述

我尝试使用XMPP（CCS）实现gcm服务器应用程序，但无法连接到Google服务器。
我正在尝试 http://developer.android.com中的示例代码/google/gcm/ccs.html

当我尝试连接时

  ccsClient.connect（userName，password）; 
  

我收到以下错误：

  gcm.googleapis.com:5235例外情况：XMPPError连接到gcm.googleapis.com:5235。 ：remote-server-error（502）
  - 由：XMPPError连接到gcm.googleapis.com:5235。：remote-server-error（502）XMPPError连接到gcm.googleapis.com:5235。

我使用服务器密钥API密钥（密码）
和用户名=项目编号+@ gcm.googleapis.com

我的项目被列入白名单，用于上游消息
被认为关闭的港口在我的工作场所开放。 5228,5292和5230为我的IP。
我应该用它来开放端口吗？公共Ip或另一个？

可能是什么问题？
请帮我解决这个问题！提前致谢 您可以尝试从命令行 - 例如
telnet gcm.googleapis.com 5235

如果您看到已连接到gcm.l.google.com - 您的防火墙很好。

CCS（由第三方服务器使用的XMPP端点）正在使用端口5235 -
连接到GCM的android / chrome设备需要5228,5229端口。

< AFAIK 5230不是我们的港口之一，不知道你是如何得到它的。

I am trying out implementing gcm server application using XMPP(CCS) and i cant able to connect to the google servers. I am trying out the sample code from http://developer.android.com/google/gcm/ccs.html

when i try to connect

ccsClient.connect(userName, password); 

i get the following error

I am using server key for the API key(password) and username="project number"+"@gcm.googleapis.com"

My project is whitelisted for upstream messaging Ports considered to be closed are made open at my workplace. 5228, 5229, and 5230 for my IP. which Ip should i use to open up the ports? public Ip or the other one?

What could be the problem? Please help me resolve this! Thanks in advance

解决方案

Can you try from the command line - for example "telnet gcm.googleapis.com 5235"

If you see "Connected to gcm.l.google.com" - your firewall is good.

CCS ( the XMPP endpoint using by 3rd party servers ) is using port 5235 - the 5228, 5229 ports are needed for android/chrome devices connecting to GCM.

AFAIK 5230 is not one of our ports, not sure how you got it.
