My domain onyx-drift.com is stuck on a 404 error, even though Vercel's internal checks confirmed: 1. \*\*Build is Successful\*\* (Output: client/dist/index.html is confirmed). 2. \*\*Deployment is READY\*\* and manually promoted to production. 3. \*\*The issue is on the platform side\*\* (routing/deployment mapping). I cannot submit a ticket due to my Hobby plan. Please help resolve this Edge Network issue immediately. Pauline P.

Here are the relevant details based on your guide: * **Domain Configuration:** My domain shows a **'Valid Configuration'** status in the Vercel dashboard. * **Observed Error:** I am getting **\[Mention the exact error here, e.g., a browser-specific DNS Error/No Response, OR the Vercel white 404 screen with its specific Code and ID if you see it\]**. It seems my site is not reaching the Vercel Edge Network successfully. * **Project Details:** For your internal review, the **Deployment URL** or **Project ID** is: **`https://onyx-drift-app-final-git-main-naimusshakib582-pixels-projects.vercel.app/ **Failing Custom Domain:** My custom domain is consistently showing the 404 error: 👉 **[Custom Domain]:** `https://www.onyx-drift.com/` (or `onyx-drift.com`) `** Could you please check the **routing and DNS propagation** for this specific deployment internally? Your help is greatly appreciated. Thank you."
