What is the problem?
Just update OctoPrint to latest and now getting Undervoltage error. Was not getting Undervoltage error before upgrade and had no issues.
What did you already try to solve it?
Re-boot and try again.
Have you tried running in safe mode?
No
Did running in safe mode solve the problem?
N/A
Systeminfo Bundle
You can download this in OctoPrint's System Information dialog ... no bundle, no support!)
