Octoprint suddenly cannot autodetect serial port on CR-10


#1

What is the problem?

I get the error message " Error: Failed to autodetect serial port, please set it manually." despite having gotten it to work perfectly last night.

What did you already try to solve it?

Restarted printer/raspberry pi multiple times, unplugged and plugged back in printer
