Digital Business Card Showing "Site Not Found" (404 Error)

My Netlify-hosted digital business card is no longer accessible. When I open the website, it displays the message:

Site not found

Looks like you followed a broken link or entered a URL that doesn’t exist on Netlify.

The site was previously working correctly. I have not intentionally deleted the site or changed the domain. Please help me identify why the deployment or domain is no longer available and restore access if possible.

Site URL:
