Why am I not authorized to launch a game?

When you press the 'Play' button, Sora Stream reserves space on one of our servers so that you can enjoy the game. After a few seconds, that space is freed so you and others can still enjoy Sora Stream.

The message 'Not authorized' can appear when you are trying to open a game whose space has already been freed. This usually happens in Windows when it has taken a long time to accept for the browser to open our application.
