What is the problem?
Since running the update installer for 1.5.2, I've been having trouble getting my browser to talk to my Octopi. I will run a print, and it will work just fine, but after the print has completed, I can no longer see the Octopi through the browser. It takes up to an hour for the browser to access the server again, regardless of whether I restart the server or not. Frustratingly, sometimes when I restart the server, I hear the the telltale "click" of the server connecting to my printer, but the browser will say "Looks like something went wrong during startup, the server is gone again. You should check octoprint.log."
What did you already try to solve it?
I am very much a newbie when it comes to this sort of thing. I haven't known what to try aside from restarting the server and trying to run it in safe mode.
Have you tried running in safe mode?
Did running in safe mode solve the problem?
