Hi Railway team ,

I’m facing an issue with a custom domain setup and would appreciate any guidance.

Situation:

• I previously used my domain happychild.in on Vercel.

• I completely deleted the Vercel project and removed the domain from Vercel.

• Now I have fully migrated the project to Railway.

Current status:

• My Railway default URL works perfectly and www.happychild.in:
  https://backend-production-0d93.up.railway.app

  www.happychild.in

• But when I open:
  https://happychild.in
  I get:
  404: DEPLOYMENT_NOT_FOUND

DNS Setup:
I’m using Cloudflare and I’ve configured:

• happychild.in → CNAME → 7ufpt70s.up.railway.app

• www.happychild.in → CNAME → b9uz0xyd.up.railway.app

• Proxy status is DNS only (grey cloud)

I already:

• Deleted old Hostinger nameservers

• Purged Cloudflare cache

• Re-added domain inside Railway → Settings → Domains

Railway now shows Setup complete, but the domain still throws DEPLOYMENT_NOT_FOUND.

Suspicion:
It feels like the domain might still be cached/associated somewhere from the old Vercel deployment, or Cloudflare is holding old routing.

Question:
Is there any internal Railway step required to “force refresh” or reattach a domain that was previously used on another platform?

Any help from the team or community would be greatly appreciated
