After updating the filamentmanager update, server restarted and i got tha message.
What did you already try to solve it?
I have tried to force install the plugin and nothing happened.
After that i have tried a solution i found here (turn to safe mode and delete a file from the plugin folder),
Nothing happened also and the plugin folder was empty already
Have you tried running in safe mode?
yes
Did running in safe mode solve the problem?
no. I am pretty sure that it doesn't turm to safe mode cause i get the same message at my browser: "The octoprint server is currently not running"

Additional information about your setup
OctoPrint version, OctoPi version, printer, firmware, browser, operating system, ... as much data as possible
log file
The last entries in the log are from 2021-11-16, followed by a lot of corrupted-looking stuff. So something is wrong that means it can't start up properly.
Presumably you have SSH access to the Pi to get the log file etc. already. So from SSH, if you run ~/oprint/bin/octoprint serve do you get any output?

There was a fatal error starting up OctoPrint.

Ok, that gives us something to work with. It means there's a problem with your config.yaml file. Don't post it here as it contains secrets, but you might want to open it to see what the problem on line 201 is. It might have ended up the same as the log file, with corruption in it.
