This is a copy of the guide found at https://reprap.org/forum/read.php?415,814275 Read that if you want to know why the following steps might help you get rid of the problem.
- Select the radiobutton labeled "Ignore" under "Settings -> Serial Connection -> Behavior -> Error Handling -> What to do on firmware error".
- Restart Octoprint either through the navbar power button or via an ssh terminal "sudo service octoprint stop"
- Reset/reboot your printer.
- When the printer has finished rebooting, Connect with Octoprint. It may take a moment, but that is to be expected.
- In the Terminal, issue a M502 command to factory reset the firmware to clear out any lingering data.
- In the Terminal, issue a M500 command to factory reset the firmware to reset the EEPROM.
- Verify by issuing an M503 command to report the settings stored in the EEPROM.
- If you wish, test the EEPROM editor plugin.
- Once satisfied that this worked, re-enable the default Octoprint setting by selecting "Disconnect from the printer" in step one.
I got this problem with my Creality Ender 5 Plus 'out of the box'... this was the output in terminal when I tried to connect:
