I purchased a domain (panabarbero.com) in Cloudflare some time ago and I've been developing my project ever since and have moved over hosting providers, between Cloudflare itself to Vercel and now I want to host my whole infra on Railway, but when I assigned the custom domain and added the DNS records on Cloudflare I loaded my site but it throws net::ERR_CERT_COMMON_NAME_INVALID and doesn't let me access it.

SSL configuration is set to Full only.
