I get that all the time on my phone. It may be because it is not updated, or it is old and the port broken. It especially does not work while I'm on the destiny app. Try unplugging it and plugging it back in, cleaning off all the dust, and/or getting a new charger,and/or a new I pod or getting it fixed.
