That's a PHP thing -- perhaps make the directories, or perhaps configure
your PHP to use a different directory. PHP documentation should indicate
how.

The config you showed only uses /home/ubuntu/htdocs/public_html as the
document root for requests that end in .php.

The request /js/dragdrop.js is not handled in this location. The
configuration in, or inherited into, the location that handles
that request is the one that matters. And that, presumably, has
/home/ubuntu/htdocs as the configured document root.

Possibly setting "root /home/ubuntu/htdocs/public_html;" at server{}
level will cause things to work for you.

Cheers,
