I had Octoprint running for months with no issues. I had to switch Raspberry's - I was on a B3+, now it's on a B3. I reinstalled Octoprint on a new SD. No other changes. When I start Octoprint on my PC, the Prusa i3 MK3S+ restarts. I see this for State on the PC:
State: Offline after error
No more candidates to test, and no working port/baudrate combination detected.
It's a clean install with no plugins yetso I don't know what to check.
not sure how.
You can download this in OctoPrint's System Information dialog ... no bundle, no support!)
OctoPrint version=the latest, OctoPi version=the latest, printer=Prusa i3 MK3S+, firmware=DK, browser=firefox, operating system=Win10,
