Who updates and manages the TLS certificates?

If a valid DNS record was used to obtain the TLS certificates, Kuroco will automatically update them.

Kuroco uses Let's Encrypt for its TLS certificates.

Certificate management

Certificates issued by Let's Encrypt are valid for 90 days.
Kuroco re-verifies DNS records and renews certificates approximately 30 days in advance.
If the DNS record for obtaining the TLS certificate is not specified by Kuroco, or if the CAA record blocks Let's Encrypt, the certificate will expire at the end of the 90-day period.
Kuroco will notify you of the impending expiration date by e-mail 30 days in advance.

If the DNS record and the CAA record are both valid, but the certificate renewal still fails, please contact our Support Team for assistance.
