Vite build giving 404 errors on critical elements

[CrawfordW]

Getting 404 error (Not Found) on these two files, even though they are present:
assets/index.63ea4fab.css
assets/index.a881ef79.js
This is a Quasar app that worked fine when built with Webpack.
Note: it works when opened with the dev server created by quasar cli, but does NOT work on 3 other servers including the one an my hosted website. Any help will be appreciated.

I have a similar problem. In my case, when I navigate to dist/index.html, DevTools shows the 404 on the js file, but not on the css. I believe that the most likely cause is urls inside the built file that haven't been re-written to reflect the changed location of the calling file. My app is vanilla javascript that uses custom elements. I'm not sure how to fix this or if it is fixable.
