Server disconnect timeout

Hello. I have android game with photon. Android games is not working in background (android specific)
When i hide(minimize) the game, after 10 seconds i have on server:

OnDisconnect - ConnID=52 reasonCode=ClientDisconnect
Connection state changed from Connected to Disconnected
OnDisconnect: conId=109.195.243.29, reason=ClientDisconnect, reasonDetail=
IUMobilePeer: User disconnected
Connection state changed from Disconnected to Disposed


On client (when i open the game (maximize)):

PhotonDebugReturn: Receiving failed. SocketException: WouldBlock
Status code:InternalReceiveException
Status code:Disconnect


How can i increase timeout?

  • Hi @GLeBaTi,

    If you want to debug Photon clients connected to self-hosted Photon Server visit this link.
  • @JohnTube thanks for reply
    I am not using PUN (i am using PhotonPeer directly)
    InactivityTimeout = "0" not solve my problem :/
  • I assume you are using native sdk for android, right?

    No, i am using Photon Unity3d SDK
  • I found in "https://doc.photonengine.com/en/realtime/current/reference/known-issues" :
    Mobile - Home Button Causes Disconnect

    On (most) mobiles, applications are not allowed to keep a connection when they are in the background. There are next to no exceptions to this rule (e.g. see Background Execution on the Apple dev pages).

    When a game gets focus again within (approximately) 10 seconds, PUN will try to continue the game. Any pause longer than that will lead to a timeout. There is a chance that the server side timed out the client meanwhile.

    Due to the nature of iOS also shutting down the app immediately, a "timeout disconnect" callback naturally gets known to your app only when it's executing again.

    There are system callbacks by iOS when an application goes to the background and when it gets focus again. Use those to disconnect. If the game design can allow a player to return even after several seconds or minutes, then you could also re-connect and join the game again.
  • @GLeBaTi is there a reason why you use the "low level" PhotonPeer "directly" from the Realtime Unity SDK? Why not use LoadBalancingClient (extend it maybe?) or LoadBalancingPeer?

    Currently, the background thread is available in PUN only.

    @Tobias what do you think?
  • Becouse i have only one server. I don't need load balancing/
    background threads also not working in background in android.
    Now i make reconnect on game gets focus again.
  • Bump... any updates on this guys?
    I too am facing the same issue.
  • hi, @sid_juego
    you may either reconnect as @GLeBaTi did
    or ask in dotnet client forum.

    best,

    /// Defines how many seconds PUN keeps the connection, after Unity's OnApplicationPause(true) call. Default: 60 seconds.

    ///
    /// It's best practice to disconnect inactive apps/connections after a while but to also allow users to take calls, etc..
    /// We think a reasonable backgroung timeout is 60 seconds.

    /// To handle the timeout, implement: OnDisconnectedFromPhoton(), as usual.

    /// If you need to separate this case from others, you need to track if the app was in the background

    ///
    ///
    /// Info:
    /// PUN is running a "fallback thread" to send ACKs to the server, even when Unity is not calling Update() regularly.
    /// This helps keeping the connection while loading scenes and assets and when the app is in the background.
    ///
    /// Note:
    /// Some platforms (e.g. iOS) don't allow to keep a connection while the app is in background.
    /// In those cases, this value does not change anything, the app immediately loses connection in background.
    ///
    /// Unity's OnApplicationPause() callback is broken in some exports (Android) of some Unity versions.
    /// Make sure OnApplicationPause() gets the callbacks you'd expect on the platform you target!
    /// Check PhotonHandler.OnApplicationPause(bool pause), to see the implementation.
    ///


    and now, where exactly is "PhotonHandler.OnApplicationPause" ??
