Let’s Encrypt certificates are verified automatically if the following conditions are met:
A certificate is going through the renewal procedure and its status is Renewing. The certificate renewal procedure is initiated 30 days before it expires.
The certificate is used in the HTTPS configuration of a static website in Object Storage.
For each certificate domain, the following is configured:
An alias for the static website bucket where the certificate is used.
Or a redirect to the domain with the alias for the bucket.
The certificate is not a Wildcard certificate: it doesn’t contain masks for subdomains.
