I am using octoprint since month now without any issues.
After a Firmware update on the printer, the printer setting RPI port ON changed to OFF (without my recognition) and octoprint was not able to connect anymore (obviously).
Unfortunately I searched on wrong places and after changes I made in several files I rebooted the system multiple times... once after each change. After the last reboot octoprint seems not to load anymore... Revert all changes but no success to load octoprint.
Interestingwise there is NO log entry anymore in octoprint.log since the last regular shutdown of the last reboot.
What is the problem?
Octoprint do not start anymore. No entries in octoprint.log since shutdown
What did you already try to solve it?
Revert all changes, multiple restarts, multiple manual octoprint start tries (sudo service octoprint restart/start), tried adding start in safe mode in config.yaml
serial.log or output on terminal tab, browser error console ...)
