"Timing out" is delayed when app is in background and not closed

I did set the timeout to 2s but when the app on android is in background, it's going to overload the msg queue this way :



Then, i will "timeout", the problem is it takes about 1.1 minute to get disconnect.

But when crashing the games it takes only few seconds.

I just want the app to start timing out right after it goes in the background.

Thanks for your help.
