Error on disconnect

Hi, I'm making a mobile game that allows you to continue in single player mode if a multiplayer game ends prematurely. However, if internet connectivity is lost, I get an endless stream of errors from PhotonVoiceNetwork which affects performance. I'm currently solving it with:
public override void OnDisconnected(DisconnectCause cause)
{
	if (Photon.Voice.PUN.PhotonVoiceNetwork.Instance != null)
		DestroyImmediate(Photon.Voice.PUN.PhotonVoiceNetwork.Instance.gameObject);
}
But I'm curious if that causes issues if someone's connection flickers, or if there's a way Voice can handle this error a little more gracefully? Here's the full error:

  • Hi @lmartell,

    I see.
    What is the disconnect cause here?

    You could fix this using a proper solution not a workaround if you know why the client got disconnected in the first place.

    - If both clients PUN 2 and Photon Voice 2 disconnect then this should not happen
    - If Photon Voice 2 disconnects and PUN 2 does not (unexpected), Photon Voice 2 will keep retrying to reconnect if PhotonVoiceNetwork.Instance.AutoConnectAndJoin is true
    - If PUN 2 enters offline mode, this depends on PhotonVoiceNetwork.Instance.WorkInOfflineMode

    so I would adjust values PhotonVoiceNetwork.Instance.AutoConnectAndJoin and PhotonVoiceNetwork.Instance.WorkInOfflineMode. maybe at compile time or change them on the fly at runtime.
    log disconnect cause(s).
    maybe have a retry attempts threshold after which you stop.

    You could also explicitly try calling PhotonVoiceNetwork.Instance.Disconnect.
  • I first ran across the error when my router crashed, but after that I was simulating it just by disabling my network adapter, so disconnect cause is just "Exception." If I disconnect the cable then cause is "Client Timeout" after a few seconds, which is what I'd expect. The repeating error is the same in either case.

    I actually had some issues updating the voice plugin last week... I'm on 2.18 before WorkInOfflineMode was added, but started a separate thread for that and circle back once that's working.

    Thanks!
