I have noticed that when left unattended my RPi with OctoPi goes completely offline and becomes unresponsive. The RPi lights are on, the USB Wi-Fi is not blinking, but I can't ping or connect to the host neither via SSH nor with HTTP. The only thing that helps is pulling the micro USB power out and rebooting the RPi. It looks almost like the RPi is sleeping, but since there is no keyboard or monitor attached to it, it is hard to say.
I poked around the OctoPi settings and RPi settings but did not find anything that configures sleep cycle / timeout etc.
My OctoPi/Print version: 1.3.8
Any ideas what might be going on? Anyone else experiencing the same issue?
