Linerender/Raycast2D colliding inconsistently with sprites

Hi,

I have a laser beam that bounce of 2D tiles inconsistently.

On some part of the tile the laser bounces correctly, the Vertices count is correct but the collider is not detected.

On some other part of the same tile the laser dies, the Vertices count goes up to LaserMaxReach+1 and the collider is detected.

(If I use Raycast instead of Raycast2D and 3D colliders on sprites the laser works perfectly, but I need 2d colliders since other parts of the game work with them)

What is wrong in my code? Thanks
