Try this one to get image path and then after pass that path to image scr.
<?php
$image_id = get_post_thumbnail_id($post->ID);
$image_url = wp_get_attachment_image_src($image_id,'large', true); ?>
<a href="<?php the_permalink(); ?>"><img src="<?php echo $image_url[0]; ?>" />
</a>
<?php
}
?>

Try to used
get_the_post_thumbnail( $post_id, 'thumbnail' );
If you want to get thumbnail with custom width and height then used below code

In array first element for width and second for height.
