asmack BOSHConnection无法连接

Question

我正在使用：asmack-android-19-0.8.10.jar

开发Android聊天应用

服务器端正在使用BOSH协议并发送此类数据：

{
    "Domain":"domain",
    "boshUrl":"http://domain:7070/http-bind/"
}

我这样连接：

BOSHConfiguration  configuration = new BOSHConfiguration ("domain");
configuration.setSASLAuthenticationEnabled(false);
BOSHConnection connectionBosh = new BOSHConnection (configuration);
connectionBosh.connect();

我有一个XMPPException： Timeout reached for the connection to null:0.: remote-server-timeout(504)

我做错了什么？

谢谢！
