I’m unable to connect a custom DNS domain on Railway. The deployment process is being blocked due to what appears to be a Valve-related issue (possibly in the networking or deployment routing layer). I need help identifying the cause and fixing it so the domain can be successfully configured.

• xplanation of what the “Valve” issue means in Railway

• Step-by-step solution to connect a custom DNS domain successfully

• Any additional configuration required (e.g., CNAME, A record, timing, SSL)

I'm not too sure what you meant by "valve" but how is your DNS configured?

If you want to map your own domain to Railway's deployment, you can do so within service settings under the Networking tab by clicking on Custom Domain then adding a CNAME record to your DNS provider with the given CNAME domain to use.
