We are currently experiencing an issue in FKL2 where all players are unable to enter the game, with the error message "Matchmaking Error (#2)". This issue was caused by the UEFN v40.0 update. We are actively working on a fix and have reached out to the UEFN team for support. We appreciate your patience while we resolve this. Compensation will be provided to all players once the issue is fixed. Thank you for your understanding and support.
