What is the problem?
After reboot Octoprint or power off the Raspberry (mine is a PI 3B+), Octoprint didn't restart. Some seconds after power on the Raspberry, I can see its IP in my Network, but after a short time, it disappears. It seems that it starts the boot system, but can't go on.
What did you already try to solve it?
I tried turn off and turn on the Raspberry, but not working. The only solution for me until now is flashing again the firmware. But it is so annoying, because I need to format the SD card, reinstall the Octoprint and re-configure over and over again. I would like to know a solution that is no need more reinstall the system.
serial.log or output on terminal tab at a minimum, browser error console if UI issue ... no logs, no support! Not log excerpts, complete logs.)
