Light(Shadow) dissapears on distance

Hello, my game on my pc(editor) works fine everything but when i export it to Android and when my player moves towards my light dissapears slowly and there are no shadows anymore.
I can see its not that dark but there are none shadows.

Im using directional light, i tried even the light to follow the player but thats not working either

How can i fix this?

I Fixed this with disabling the fog
