gamelobby_ended without any cause

I'm using playfab for more than 1 year now developing with external servers.

But since a couple of days my servers end on their own, even when no actions are made, without any visible causes after approximately 2 minutes. I invite you to check on our game E347, you can see a long game_start, game_ended list of events with a 2-3 minutes interval

There is only one path in code I call deregister and no breakpoints triggers there.

Here is the type of gamelobby_ended event I can see on playfab event stream.

{
    "EventName": "gamelobby_ended",
    "EventNamespace": "com.playfab",
    "EntityType": "gamelobby",
    "Source": "PlayFab",
    "TitleId": "E347",
    "GameMode": "GM_MATCHMAKER",
    "Region": "EUWest",
    "ServerBuildVersion": "main_build",
    "ServerHost": "127.0.0.1",
    "ServerIPV6Address": null,
    "ServerPort": 20120,
    "ServerHostInstanceId": null,
    "Tags": null,
    "EventId": "ec5da43e2f3141b2ac35ee6a46262537",
    "EntityId": "9FA94BF5FAB432B2",
    "SourceType": "BackEnd",
    "Timestamp": "2017-12-19T17:13:40.8270592Z",
    "History": null,
    "CustomTags": null,
    "Reserved": null
}

Is there something new on your side or am I missing something ?

We have looked up the counter for it and we can confirm that termination of your lobbies was due to lack of heartbeat.

The heartbeat is required every 2 minutes. If the game server does not phone into our system we assume it is not healthy and we terminate it.

For more details, please see: https://api.playfab.com/docs/multiplayer-servers

Bringing in Discovery

PlayFab maintains a registry of all game instances running and which players occupy the slots in those games. To achieve this, each server instance should Register with PlayFab, post an occasional Heartbeat, and Deregister itself before termination.

Can you confirm it's indeed a new and recent behaviour? It'll be easier to troubleshoot.

Yes, the timeout on the heartbeat for externally hosted servers was only being applied in cases where we'd been notified that the title was using external servers previously. We've since updated to have the timeout work as described in our documentation and tutorials consistently.

Adding RefreshGameServerInstance did the trick. Again, we really appreciate the customer service, though prior communication would be of great help. Don't you have a technical newsletter ?
