Public Matchmaking Bug: Unable to Join Public Lobbies - New Fortnite Maps

General Issues and Bug Reporting
, , ,
1

Summary

Players attempting to connect to my games, Brawl Box 3v3 and Brawl Box 5v5, are unable to do so due to the error: ‘Matchmaking Error #1, Unknown Error, Maybe Try Again?’ This means that no matter how much external advertising, marketing, or any form of promotion I do, my game will not pick up players. I’ve already troubleshooted the settings several times, and each time, the same result. (And yes, Custom Teams is not enabled with Dynamic Matchmaking)

Looking at the logs they are all the same Queue Full error

Now the island above has logged in something intermittent?

Wow, thank you so much for this :open_mouth:, I’m not too sure why it’s saying Queue Full error either. At one point, this map WAS playable (Brawl Box 3v3) so I’m not sure what happened…

Update: Both maps now work, not sure why they weren’t before. Thank you so much for the help!
