I've got a brand new Raspberry Pi Zero W and have a problem. I don't think this is specific to the PiZero as Googling has revealed this to be problem with other Pi's. I've got the Pi configured with Raspbian Jessie, and running Pi-Hole, including the ssh server. When I first boot up the Pi, I can connect to it via ssh from my mac fine, connect to the Pi-Hole web server, etc. However, if left alone for awhile (not sure of duration) I can no longer connect with SSH or the browser. The Pi is still running as it's performing it's Pi-Hole functions, I just can't connect again.
Does anyone have any ideas, suggestions, or pointers how I resolve this issue?
