Terrain doesn't collide with my mesh

I have a player with mesh collider and a terrain with terrain collider.
My player has rigidbody attached wich is Kinematic. In the mech collider, the IsTrigger is checked. I have an other cube, with cube collider.

If i go through the cube, in the log i see “Colled”, but if i go through the terrain, i cant see anything.
My code is here:

void OnTriggerEnter(Collider col) {
        Debug.Log("Colled");
}

void OnTriggerExit(Collider col) {
    Debug.Log("Exit");
}

void OnTriggerStay(Collider col) {
    Debug.Log("Stay");
}

I want to see Colled in my Log, if i go through the terrain. Thank you for the help!

Try to make you mesh collider(your object) a convex mesh. The problem probably is that you are trying to collide two mesh collider(the terrain collider is a type of mesh) which I remember right it won’t collide, but when you are hitting the cube you have a primitive which fires correctly. So try to make your mesh collider convex(you can tick in the inspector) or try to replace with a primitive collider and try it out that way.
