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，但当我通过调用[xmppRoom joinRoomUsingNickname]加入一个房间时，流会断开连接而不会出现任何错误。
我也实现了xmppStreamDidDisconnect:withError，但它仍然给出了nil错误。由于流断开连接，用户在加入房间后也会立即离开房间。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。
我正在使用pidgin来测试它，但它在那里工作正常。什么可能是立即断开连接的原因？
PS：我正在iOS 9上运行的iPhone 5上测试它
更新：现在出现以下错误 -
错误Domain = GCDAsyncSocketErrorDomain Code = 7“Socket由远程关闭 peer“UserInfo = {NSLocalizedDescription =由远程对等方关闭的套接字}
