Additional information about your setup
OctoPrint version, OctoPi version, printer, firmware, browser, operating system, ... as much data as possible
Running the newest Octopi version as I just reflashed it today and the issue persists. Running an Ender 3 with stock firmware and Pi 3B. I start a print and the Pi will disconnect from the printer, sometimes after a few minutes, sometimes after a few hours. The only thing that changed when the issue started is I had moved the printer from my house to the garage
