Let's encrypt certificate can't renew


Ubuntu 20.04 VPS, nginx, let’s encrypt certificate installed on January (not wildcard), automated by certbot version 1.13.0 .
“sudo certbot renew --dry-run” doesn’t work anymore, it returns:

Failed to renew certificate with error: Error determining zone identifier for 403 Client Error: Forbidden for url: https:/
/ (Are your Application Key and Consumer Key values correct?)

The renewal is done by the dns-ovh certbot plugin.
File /etc/letsencrypt/renewal/ has the same credentials used when I created the certificate.

How can I check if my credentials are valid?
Could this issue be related to the recent OVH incident?


From the error message, it looks like your API key has expired.

Maybe you should generate new tokens at the following URL:

  • Application Key
  • Application Secret
  • Consumer Key
