Asked the AI chatbot this question, and was told that it requires a manual answer.

Site name: ftd-tools.netlify.app  
Custom domain: [tools.federaltaxdesk.com](http://tools.federaltaxdesk.com)

DNS verification was successful, but when I click “Provision certificate” I get the error: “certificate parameter is required when updating an existing certificate.”

Please manually clear/reset the stale TLS/SSL certificate state for my site so I can provision a fresh Let’s Encrypt certificate.
