Terminal does not work

What is the problem?

When I print code in the terminal section I recived error massage and the printer doesn't doing anything. The massage looks like this:
Send: M106
Recv: echo:Unknown command: "V/V/V/V/V/V/V/V/V/V/V/V/V/V/V/V/V/V/V/V/V/V/V/V/V/V/V/V/V/V/V/V/V/V/V/V/V/V/V/V/V/V/V/V/V/V/V/V"

What did you already try to solve it?

I have updated all the recommended updates, and also restart the machine and octoprint couple times. More than that i have tried to play with the letters, but it doesn't seem to do changes to it. I recived the same erroe massage for every code I printed.
