Cannot connect to matchmaking when using WebGL

Hi there,

I'm trying to run the NetworkStarter project from here: http://forum.unity3d.com/threads/unet-sample-projects.331978/

And it's working fine on the editor (I also set my own cloud id in player settings)

But on WebGL, it says this in the console: Failed to read the ID for the match maker, please set the Cloud Project ID string in the Player Settings (see https://unet.cloud.unity3d.com).

The strange thing is that it's only on WebGL and for the rest it works...
