Neither the required CNAME nor the TXT verification record is currently resolving for energy.andespower.com. The domain's nameservers are parking nameservers (Afternic), so DNS records you've added may not be taking effect. You'll need to point the domain to a DNS provider where you can manage records, then add the CNAME and TXT records shown on the domain's settings page in your Railway project. Once both records propagate, verification and certificate issuance will proceed automatically. Reply here once the records are in place and we can re-check.

you are right, the correct domain is energy.andespower.co, it had a typo

The domain added to your Railway project is energy.andespower.com (the typo), but your DNS records (CNAME and TXT) are correctly configured for energy.andespower.co. Remove energy.andespower.com from your service's custom domain settings and add energy.andespower.co instead. Verification and certificate issuance should proceed automatically since both records are already propagated for the .co domain.
