There was a timeout while trying to connect to the printer
Changing monitoring state from "Connecting" to "Offline"
Connection closed, closing down monito
From the octoprint.log file you posted, in the zip, the octopi server in unable to connect to your printer, so you need to fix that first, it may help if you enable serial logging to get a better idea of what is failing.
