Reasons Behind Fortnite Error Code 401

This error occurs due to problems with a custom game. 

It can come with the error message “match.custom key not_supported.401”, or even “Custom matchmaking key is not supported”. 

The reasons behind this problem for this Fortnite matchmaking error for custom games can vary:

  • There’s an issue with your Fortnite game or device trying to access the custom game code, so you’re getting hit with Error Code 401
  • The match-making region doesn’t match with the players that are trying to join your custom game
  • Fortnite’s servers may be experiencing an issue causing Fortnite Error Code 401

Do note that to create a custom game and not hit a Fortnite matchmaking error for custom games, you must have an Epic Games creator code first. 

You can obtain this here but do remember there are rules for obtaining a creator code, the most notable one being you need to be a content creator and have at least +1000 subs/followers on social media.

If you don’t, then you won’t even be able to create a custom game in Fortnite. But if you’re only trying to join a custom game instead of creating one, don’t worry the solutions below cover all problems and issues.

Restart Fortnite and Device

To fix Fortnite Error Code 401, the first step is to restart the game and your device. This basic troubleshooting has been effective for some players, but it's not a guaranteed solution for all scenarios.

  1. Exit the game.
  2. Right-click on the Taskbar and select Task Manager.
  3. In Task Manager, go to the Processes tab.
  4. Locate and select any Fortnite processes, then click End Task.
  5. Do the same for any Epic Games processes.

After completing these steps, reopen Fortnite and try setting up a custom game to see if the issue is resolved. If not, restart your device and then launch the game from the Epic Games launcher.
