Your domain dev.alphawoman.mx currently resolves to an A record at 54.38.220.85, which is not a Railway IP, and no TXT verification record exists at _railway-verify.dev.alphawoman.mx. The nameservers for alphawoman.mx are ns1.emailverification.info and ns2.emailverification.info, which are not Cloudflare nameservers, so any DNS records you configure in Cloudflare are not being served. You'll need to either update your domain's nameservers at your registrar to point to Cloudflare, or add the CNAME and TXT records directly with whichever DNS provider controls those nameservers. On our side, the domain is correctly registered as dev.alphawoman.mx (not as a root domain), and the CNAME target 39uhts9n.up.railway.app is showing as propagated internally, but verification cannot complete until the TXT record is reachable.
