September 1, 20233 yr I'm running Octoprint on Orange Pi Zero 2 and Armbian 22.11.3 Bullseye with Linux 4.9.318-sun50iw9 (other than assorted added userspace software, it's stock Armbian, no recompiled kernel or anything like that). It works great - while it works. I successfully complete 30+-hour prints. I can connect, monitor, everything is fine and dandy. When I'm connected to Octoprint from PC, monitoring of the 3D printer enabled, even without printing anything, it works ok. But if I'm not connected, and the printer is doing nothing for a prolonged time (an hour or so?), it stops working. Probably goes to sleep - stops responding to any network communication. Since it's a fully headless setup - no keyboard/mouse - I can't really tell for sure, it's completely unresponsive for all intents and purposes. No ping, no ssh, no www. I need to power-cycle it to be able to connect again. Any suggestions how to solve that?
