I am receiving “FleetCapacityExceededException” when calling “CreateGameSession” in a situation where I have only one instance in a single fleet. There are no active game sessions and the fleet is in “ACTIVE” state. I also checked on the instance itself that the process had successfully called “GameLiftServerAPI.ProcessReady”. I was able to play two sessions before running into this issue, both of which now appear as “TERMINATED” in the game session list for the fleet (the second game session had one player session that timed out).
Any ideas what could be happening here?
