Firebase Hosting - custom domain - Site Not Found

Question

I'm using Firebase Hosting to host my site with a custom domain. I kept getting the error "Site Not Found," as shown below. I have CloudFlare as my domain provider, where I have configured the DNS records correctly, as Firebase is shown to be connected. I also used whatsmydns.net to check, and my DNS records have propagated globally. At this point, I don't know what else to do, I have tried various approaches, such as running firebase init, npm run build, firebase deploy --only hosting, as well as remove and add the domain on Firebase Domains. I would really appreciate your help!

Answer 1

Deleting and re-adding custom domain did the trick for me.
