Fortnite's new season has been rolling out for a few weeks now, and its third update is about to roll out! This is patch 20.40, which will add new features to the game, and fix some issues.
For these updates to be applied, it is necessary to carry out maintenance, e.g.: take the game servers offline while the new content is added to the game. The maintenance generally last 1 or 2 hours, depending on patch size.
Once the maintenance has started, you will then have to wait before being able to play again, until the servers are back online.
