标题: ios - XMPP Stream 在加入 MUC 房间时断开连接

我正在使用 XMPPFramework 在我的应用中实现群聊功能。一对一聊天工作正常，但是当我通过调用 [xmppRoom joinRoomUsingNickname] 加入房间时，流会断开连接而不会出现任何错误。

我也实现了 xmppStreamDidDisconnect:withError，但它仍然给出 nil 错误。用户在加入房间后也会立即离开房间，因为流会断开连接。我也在使用重新连接模块，但是当它重新连接时，房间不会自动加入。

我也在使用 pidgin 来测试它，但它在那里工作正常。立即断开连接的原因可能是什么？

PS:我在运行 iOS 9.1 的 iPhone 5 上测试它

更新:现在出现以下错误 -

Error Domain=GCDAsyncSocketErrorDomain Code=7 "Socket closed by remote peer" UserInfo={NSLocalizedDescription=Socket closed by remote peer}
