GoDaddy does not support CNAME records on the root/apex domain (@), which is a DNS standard limitation. To work around this, you can either use a subdomain like www.rsvbiotech.in instead, or switch your domain's nameservers to Cloudflare (free plan), which supports CNAME flattening and will let you set a CNAME on the root domain pointing to your Railway CNAME target. See our docs on adding a root domain for more details.
