This usually means that you have not set your Web Root to where your files are. If the webserver is pointed to a web root which does not contain any index.php (or index.html or whatever it is configured to look for) it will deny showing a directory listing and instead show a forbidden error.
Of course, you may have some bespoke configuration or script which is returning this HTTP error code, but the first thing to check here is whether your Web Root as set in Webdock is correct.
