Reporting Studio can't connect SQL server

Reporting Studio can't connect SQL server

Hi,
I learn zenon report engine on zenon academy. (https://www.zenon-academy.com/content/course/231/lesson/436/content/2296)
I have download the demo project and run service engine.
In this step, run the Reporting Studio, and connect sql server.
It's will show a error, "The connection configuration is invalid or the license server does not respond",
but I had active demo license on license management, and also can connect ZA2019 SQL server on SSMS.
How can I solve this issue?

Thanks.
