Help with video export

Hello, I am working on a project, apparently everything is going well, I only have a small problem when exporting the project.

The video is not exported, I leave a capture of the code that I use for the reproduction of the video and it looks perfect in app blocs:

however when exporting the project the video folder is empty, I tried placing the video in the empty folder, but still does not work in the browser, likewise I tried to change the video route, uploading the video directly to the server and using that route for the video but even so I can not make it appear in the same way I have reviewed that this little legend comes out:

HTTP load has failed with status 404. Media resource load has failed

The loading of all candidate resources has failed. Paused media upload.

I hope someone can help me with this little problem… the page is: www.guiafivedishes.com
