DNS CNAME Update Not Reflecting – Railway Deployment

I have updated my DNS as follows:

  • Type: CNAME

  • Host:www

  • Value:xxxxx.xx.railway.app

However, I’m still facing these issues:

  • The domain is not resolving correctly

  • The website is still redirecting to the old destination

My questions:

  1. Is this just DNS propagation delay, and should I wait longer?

  2. Do I also need to add an A record for the root domain?

  3. If an A record is required, how do I find the IP address for Railway, since Railway provides only a .railway.app domain and not a fixed IP?

Additional info:

  • I’ve removed old A records

  • Only a CNAME for www currently exists

What is the correct DNS setup for Railway custom domains?

Thanks in advance for your help pray emoji

You need to add both @ and www records to your DNS provider. Note that some providers do not support CNAME flattening (Using @ as a record), so if that's the case, I would recommend you switch to using Cloudflare's DNS.

Also, Railway does not provide A records for custom domains. You're only given CNAME records to add to your DNS provider if you wish to use custom domains with Railway.
