Error in loading Jquery 3.3.1

Hi, I was trying to add summernote to my django admin panel. but after adding it to a model field, in admin panel there is a big white area with no content. In browser console I got this error and all following issues related to not loading jquery. 

GET http://code.jquery.com/jquery-3.3.1.min.js net::ERR_EMPTY_RESPONSE

How can I add this file to my local project?
