Deployed Website Showing 404 NOT_FOUND Error on Vercel

[milan-deori]

Description:-
The deployed version of the application on Vercel is currently inaccessible and returns a 404: NOT_FOUND error. This usually occurs when the deployment settings or routing configuration are incorrect, or when the deployment build fails silently without surfacing the real issue.

Possible Causes:-

• Missing or incorrect build output directory in Vercel settings
• Incorrect or missing routes in vercel.json
• The app’s entry point (e.g., index.html or server file) is not deployed
• If using Next.js, the pages or app directory might be misconfigured
• Deployment build might have failed silently (check Vercel logs)

Suggested Steps to Fix:-

1. Check Vercel project settings → General → Build & Output Settings
2. Make sure the correct Framework Preset (e.g., Next.js, React) is selected
3. If using vercel.json, ensure proper routing configuration
4. Review deployment logs to confirm successful build and routing
5. Verify that the deployed build folder matches your framework's expected output (build/, dist/, etc.)
