【问题描述】：
我正在尝试为我的应用程序制作多用户聊天。我已经完成了单用户通信的编码，它工作正常。我无法在多用户聊天中创建或加入群组。下面是我的代码。

}
在调用 join() 函数时尝试执行上述代码时出现 XMPP 错误。
multiUserChat.createOrJoin(loginUser) 这个地方出错。
XMPPError: remote-server-not-found - 取消 org.jivesoftware.smack.PacketCollector.nextResultOrThrow(PacketCollector.java:220) 在 org.jivesoftware.smackx.muc.MultiUserChat.enter(MultiUserChat.java:311) 在 org.jivesoftware.smackx.muc.MultiUserChat.createOrJoin(MultiUserChat.java:400) 在 org.jivesoftware.smackx.muc.MultiUserChat.createOrJoin(MultiUserChat.java:376)
请帮助我。提前致谢。

问题是我使用了错误的参数
MultiUserChat multiUserChat = multiUserChatManager.getMultiUserChat(roomName + "@" + serverName + ServiceConstant.XMPP_HOST_URL);我应该在这里使用XMPP 服务名称 而不是XMPP 主机url。当我将 XMPP_HOST_URL 替换为 XMPP_SERVICE_NAME MultiUserChat multiUserChat = multiUserChatManager.getMultiUserChat(roomName + "@" + serverName + ServiceConstant.XMPP_SERVICE_NAME); 时，代码运行良好
