SSL error with the subdomain `api.staging`

Dear Support Team,

I am experiencing an SSL error with the subdomain

api.staging

api.staging

, which is set up as a CNAME record on Cloudflare DNS. Despite having deployed an Amazon EKS cluster using an ingress NGINX controller and attaching a valid Let's Encrypt certificate to our load balancer, accessing routes like https://api.staging.lokalee.app/product/v2 results in the error: "Secure Connection Failed". Other subdomains are functioning correctly with SSL, but api.staging shows "This domain is not covered by a certificate". We are using an EKS cluster, and the application is a Node.js app published through an ingress NGINX controller. Could you please assist in identifying and resolving the issue?

Best regards,
Georges

Automatic universal certificate generation is only supported at the subdomain level, sub-subdomains require the Advanced Certificate Manager and setting Total TLS, see -> https://developers.cloudflare.com/ssl/edge-certificates/
