Cannot load external Javascript

When I want to load my external JS I get the following error:

DevTools failed to load SourceMap: Could not load content for http://localhost:8080/js.cookie.min.js.map: HTTP error: status code 404, net::ERR_HTTP_RESPONSE_CODE_FAILURE

the strange thing is, I did the exact same thing as in a other template where this is working.

Well “localhost:8080” and “cdjns.cloudflare.com” are hardly the same thing. You are pointing to a file on localhost, but do you have some kind of process that listens on port 8080 and is able to deliver that file?

my screenshot is the version that isn’t working and not pointing to localhost.
and the jquery remote file is working

apparantly there is something wrong with that cdjns, when I use an other it work.
