Killed: PRINTER HALTED Please Reset

What is the problem?
Total noob to octoprint, I am trying to connect my ender 3 pro but it keeps saying "Killed: PRINTER HALTED Please Reset"

What did you already try to solve it?
I already tried looking for the rest command or something but can't seem to find it, I've also shut off my printer and have restarted octoprint

Additional information about your network (Hardware you are trying to connect to, hardware you are trying to connect from, router, access point, used operating systems, ...)

For some reason one of the first things you're sending to your printer is M112 which is the gcode for emergency stop

Also there is a space missing in the M420 V1 gcode.

I guess there is something wrong in the gcode you're trying to print.

@PrintedWeezl All am doing tho is connecting the printer to octoprint and it tells me to reset, do you know what to reset and how to reset it?

Well if a M112 was sent to the printer it has to be power cycled -> turned off and back on again.

I just don't get why it was sent in the first place.
Did you try safe mode? Maybe a plugin is doing something weird

Yes, I did and it seems to work.

I had a plugin called "Emergency Stop Simplified." IN plugin by imputing "-1" it disabled the plugin and allowing me to use my other plugins.

For anyone else running into this issue. My error was coming from a checksum. When I had the serial connections on "AUTO" it failed. When I manually set them to the correct port and 115200 baud it worked no problem. Don't know why but it works
