Attempting to use a local file not vimeo or you tube

[impactcolor]

As stated in title I'm attempting to load a local file
here is my code:
<button class="js-modal-btn btn btn-solid" data-channel="video" data-video-url={{ asset('assets/video/lamination.mp4') }} ><i class="fa fa-video-camera"></i>&nbsp;Watch Video</button>

However url does not load. URL: is http://127.0.0.1:8000/assets/video/lamination.mp4 but it does not load.
Error is: http’s server IP address could not be found

Can you please tell me what I'm doing wrong?
