Hi Koffi
Except special setups (an Application acting as client of another application) you connect to a single application and the server create instances on the fly. So if you want to connect to the main application use:
rtmp://yourhost/BuiPower
This will create an instance named _default_
Now if you use:
rtmp://yourhost/BuiPower/room1
The instance name will be of course room1, and is automatically created by the main application. That means, you connect to an application, and pass an instance name if needed following this pattern:
protocol:[//host][:port]/appname/[instanceName]
So, in others words, your room1 inner folder will be never reached
