mqtt connect err: Connection not authorized(11)

连接服务器出现错误mqtt connect err: Connection not authorized(11)
检查了Product ID, Device UUID, Device Secret都应该没错。

请问还可以检查哪些地方调查这个问题？

我这也是这个问题，前面都正常，tls连接成功。就是mqtt这出错了

Hi @mike-2020
I have an issue in that I don't know how to get UUID and Device Secret. Could you instruct me to get it
Thanks
