@KK123 I suspect it’s because your livereload.js is not getting inserted into your index.html file. This is done via connect-livereload (npm package). Make sure that you have a <body> tag even though it’s not necessary for valid HTML5. Also, make sure that the last tag of your body content does not have any typos. You can verify all of this by using Chrome and looking at the elements, if you see the livereload.js <script> element commented out, that’s the problem.
