I have been away from my printer (Makergear M3) for several months and now cannot log in. Octoprint finds my printer and shows the status. When I try to log in, it doesn't find my username or password. However, the login I have always used is in a password manager so it should be correct. I see no opportunity to reset password.
What did you already try to solve it?
logging in using information stored in password manager
Have you tried running in safe mode?
I'm not experienced at this level
Did running in safe mode solve the problem?
You can download this in OctoPrint's System Information dialog ... no bundle, no support!)
Additional information about your setup
OctoPrint version, OctoPi version, printer, firmware, browser, operating system, ... as much data as possible
