"Custom domain shows as provisioned but returns 404 Not Found error"

Here's what to send Railway support:

My custom domain refextract.com is not routing to my service despite being fully configured. The domain shows a green checkmark in Railway's networking settings and DNS records are correctly pointing to nujx9756.up.railway.app (verified via dnschecker.org with global propagation). However, accessing refextract.com returns a Railway "Not Found" error page with the message "The train has not arrived at the station." The Railway-generated URL (refextract-v2-production.up.railway.app) works perfectly, confirming the app itself is running fine on port 8080. I've deleted and re-added the custom domain multiple times, and each time Railway assigns a new routing domain, but the issue persists. This started after a redeploy - the domain was working fine for 2 months prior. Request ID from error page: 4aCT3ukARsi51nA_m3s_FQ. Please investigate the routing configuration for this domain.

Hey,

The domain is working for me, but we will try to look into what might have happened.

Looks like your DNS is misconfigured?

You have an unrelated A record and the CNAME.
