I've had the same octopi set-up for several months now, today all of a sudden octopi has stopped showing up even in the router interface and while connected through LAN (it usually connects on 2.4g wifi). I've been clicking 'later' on all the updates in the octoprint page and I think the issue may stem from not updating? But then again its been fine for quite a while, so why now?
What did you already try to solve it?
Thinking that the issue was likely a network issue, I disconnected and reconnected the raspberry pi and printer multiple times to no avail. Then I tried connecting directly to the router but octopi still won't show up in the router interface (previously it would).
I have reached the conclusion that the issue is something to do with my octopi installation as neither the wifi nor ethernet cable worked.
serial.log or output on terminal tab, browser error console ...)
I'm not sure how I can get logs because octoprint won't work but I have taken a full backup of the sd card (including the EXT4 linux partition).
