Zoom Rooms Controller SDK Issues with Demo / Getting Started

I want to get the Demo for the ZRCSDK running.
I built it successfully, and if I execute it, it is running.
When I run the command to pair it, I get a Success code, but then when I run the start meeting command, I get error code 11.
This is the log from running it :
