It produced this output:

Certbot failed to authenticate some domains (authenticator: dns-cloudflare). The Certificate Authority reported these problems:
Domain: ilnation.fr
Type: unauthorized
Detail: No TXT record found at _acme-challenge.ilnation.fr
Hint: The Certificate Authority failed to verify the DNS TXT records created by --dns-cloudflare. Ensure the above domains are hosted by this DNS provider, or try increasing --dns-cloudflare-propagation-seconds (currently 10 seconds).
