Why does my Ultimaker S5 start extruding in the air?

Hi!

 

My Ultimaker S5 suddenly started extruding in the left corner and i pulling it back on my print - sometimes it result in a unusable print...

 

It does it the same place, layer by layer.

 

There is nothing there, in my Cura setup.

I have set my UMS5 back to factory settings, but it did not help.

 

I have attached pictures of the line that goes trough my print (is .

 

Have anybody else tried this? I cannot find anything similar.

 

Thank you!
