Fortnite: How to fix the Failed to query for tournament rules error

If you encounter an error notice saying "Failed to query for tournament rules" while queuing for a Fortnite tournament (for example, the All Valley Cup), the simplest method to repair it is to exit the game and try again after 15 minutes. If you've been in line for a long time and haven't received this message, you'll just have to wait. Do not restart since you will be pushed to the back of the line.

It's also a good idea to double-check that the event you're entering is still running and that you meet the eligibility rules. Start Fortnite and go to the Compete page to see when the competition begins. Here you can see when all of the scheduled competitions will begin. To see the tournaments that are starting soonest, scroll to the left. You can look over the details of each event and enter if one is currently taking place.

To compete in a tournament in Fortnite, you must have a career Epic Account level of at least 50. This is not to be confused with your Season Level, which can be accessed under the Career tab. 

You'll also need to set up Two-Factor Authentication (2FA), which you can't do in-game. Set up Two-Factor Authentication on your Epic Account by clicking this link. If you haven't already done so, you may need to create an account.
