SSL certificate stuck — "certificate parameter is required when updating an existing certificate"

Site name: lifetecnologia
Custom domain: lifetecnologia.com.br (and www.lifetecnologia.com.br)

DNS verification shows “successful” (green checkmark) and DNS records are fully propagated and correct (confirmed via external DNS lookups — nameservers, A record, and TXT record all resolve correctly to Netlify). However, clicking “Provision certificate” consistently fails with:

certificate parameter is required when updating an existing certificate

This appears to be a stale/stuck certificate record on the backend for this domain. Could a support engineer please manually clear/reset the TLS/SSL certificate state for this site so I can provision a fresh Let’s Encrypt certificate?
