In the latest days my players were experiencing some matchmaking inconsistency, specially when trying to match, sometimes none of the players could match either to a new session or an existing one via backfilling.
My dedicated servers automatically generates a backfilling ticket when the session starts, and I've noticed in the PlayStream that the backfill ticket includes all the users in the session, even though some of them are not longer in there (either exited or got kicked out for being AFK), and those users take too long to match again into another session or they timeout completely.
So I'm wondering
- Is the backfill ticket affecting the matchmaking of those players? Since they are still in the list of that ticket
- Should I cancel the backfill ticket and create another with the updated players list whenever a player exits?
- And finally, Should I make that the player CancelAllMatchmakingTicketsForPlayerRequest when it's in the main menu?
I'm using Unreal Engine 4.27.2
