The Site I just deployed won't open(page not found 404 error but local code works fine)

I just signed up with Netlify and had an existing repo from Github that I imported. I just wrote this code and it works locally on my machine. However, when I deployed the repo the preview doesn’t show the app, and it doesn’t load when I click the URL that was given to me. I changed the site name to see if that helped as well.
Site name: combo-counter-app.netlify.app
Site ID: 14573d07-c952-4159-9c87-65bec4c62232
Please advise.

Hey @TiltonD

Have you checked out this support guide?

If you are unable to solve the issue, can you share the git repository you are deploying from, and the latest deploy log.
