Hi, could you give me some more details about the problem:

• What Unity version?
• What Dissonance version?
• It looks like you were starting up a HLAPI session - if so does this happen if you install Dissonance into a new project and load up the HLAPI demo scene?
• Could you raise logging (Window > Dissonance > Diagnostic Settings) to Debug for all categories and capture a log. Preferably in the demo scene, if that reproduces the problem.

Thanks, Martin

Unity version 2018.2.9f1 (though also with 8f1) Not sure where dissonance version is, but the change log starts with v6.2.4 (2018-07-20)

I set everything to debug in Log Levels and get...Note the NULL ref in the middle. Will try loading a ne wproject with demo scene

I note that NetworkManager.singleton is null in HlapiCommsNetwork.cs line 92... Not sure if its an issue, but I do subclass NetworkManager with:

public class EANetworkManager : NetworkManager
{
}

Its still attached to a gameobject in the scene and seems to startup fine (I can use networking fine in game, send/receive data etc)

[martindevans]

NetworkManager.singleton being null will definitely be what's causing this, that's how Dissonance accesses the network system. I assume that your subclass needs to do something to initialise the singleton property properly, although I don't know HLAPI well enough to say exactly what.

[ericatkeylogic]

OK, for anyone with this issue, my problem was when I overrode NetworkManager, if you have an Awake override, it does not call NetworkManagers Awake, which fails to set the singleton and its null. Fix is to either remove your Awake(){} or call base classes function.
