Looks like you are trying to get a link to next/previous pagination results on a single(single.php) view which it doesn't make sense to me. Please refer to the docs: https://codex.wordpress.org/Function_Reference/posts_nav_link

For archive view:

For displaying next and previous pages of posts see next_posts_link() and previous_posts_link().

For single view:

For displaying next and previous post navigation on individual posts, see next_post_link() and previous_post_link().
