I flew a 8-8.5 hour flight and at landing I got a smooth landing idk around -78 or something but then my rudder pedals didn’t work but when I slowed on down and was on the grass because I couldn’t control my rudder on the runway the rudder started working on the grass
Any reason for this
(The rudder pedals have a green light when on and when I was on the runway the light was green as if they weren’t disconnected
