Can join island but not replay at the end of the game - Matchmaking error #1

Summary

On both of my FNC maps (published), I can join the map, play a full game, but then when I press “play” (actually “rejouer” - not sure of the exact term for the english interface) it fails with a matchmaking error #1. I need to go back to the lobby to be able to play again.

What Type of Bug are you experiencing?

Matchmaking

Steps to Reproduce

  1. Join the map 7199-5439-2847 (solo or with a group of friend, same output in both cases).
  2. Play a full game (3 rounds)
  3. At the end of the game, you should get the classic Battle Royale screen: press “play” (not sure about the exact term used for the english interface, I get it in french: “rejouer”)

NB: same experience with same steps for island 1110-3832-2859 (but then 6 rounds to play for a full game).

Expected Result

As in classic Epic islands, it should make a new match, and put players in the waiting zone before the new game (“welcome-like” zone).

Observed Result

Matchmaking fails with error #1. Players end being kicked back to the lobby.
Then if you go back to the lobby and join again: it succeeds.

Platform(s)

Windows
Playstation 4

Additional Notes

It has been a few weeks now I encounter this issue on both of my maps. I tried many different game configuration with no positive result.

Small overview of a few settings currently set (for 7199-5439-2847):
Teams: “free-for-all”
Team size: “equal repartition”
Max. players: 50
Min. players: 1
Overtime player target: 1

I tried rebooted my XBox as well. Friends of mine playing on Windows or PS4 get the same issue.

Thank you by advance for any help!
