Would be very nice if someone could help me with this problem
What is the problem?
Octoprint loses the connection after a while (nearly an hour) of printing when I am entering the room with the printer in it. I didn't even touched the cable or anything else.
What did you already try to solve it?
Restart printer and octoprint
changing the usb cable
serial.log or output on terminal tab, browser error console ...)
