Android中使用XMPP实现登录都可以连接上为什么登录不了

Question

//创建连接
public void conn() {
ConnectionConfiguration config = new ConnectionConfiguration("192.68.12.8", 5222);
XMPPConnection connection = new XMPPConnection(config);
try {
connection.connect();
if(connection !=null){
connection.login(account, pwd);
startActivity(new Intent(LoginActivity.this,MainActivity.class));
}else{
Toast.makeText(LoginActivity.this, "Null null", Toast.LENGTH_SHORT).show();
}
Toast.makeText(LoginActivity.this, "Login success~", Toast.LENGTH_SHORT).show();
} catch (XMPPException e) {
e.printStackTrace();
}
}
}

 输出log：
