I am trying to test a multiplayer game, so tried to open a remote preview on another device. But is always returning 'error: join failed'. That's even before connecting to the signalling server, on an 'offline' layout. I tried to remote preview some other NON-multiplayer games and always returns the same error. It is not about my multiplayer events. I cannot remote preview at all. I thought it might be something about device's webGL, but happens on every one. Could be a bug or should I set or check something on the browser, for instance?
