What is the problem?
Just upgraded the board in my ender3 to SKR v1.3. I connected the same Pi that I had been using previously to the new board and booted it up. The Pi is booting, and I can SSH to it. However, the web interface won't load. I get the "OctoPrint Server is not currently running" page when I navigate to the Pi IP address.
What did you already try to solve it?
Tried manually restarting the service (sudo service octoprint restart) but it doesn't start.
Additional information about your setup (OctoPrint version, OctoPi version, printer, firmware, ...)
Trying to avoid having to reimage the card because my new hardware case makes it very hard to get in and out of. If I can fix it from the command line, that would be ideal.
In Linux, folders which start with a period are hidden normally from standard ls commands. The one you're interested in is ~/.octoprint so that definitely would be hidden. Try:
Either scp or WinSCP are made to move files back and forth. Since you're interested in adjusting ~/.octoprint/config.yaml in-place, I don't think that's the tool I'd use. (The file is rather picky about line endings and your Windows-based computer might munge that up for you.)
