Is their a problem with one of your DNS test server?
Since 2 days I have a problem to get certificates
I have tried dnsckecker and it seems Online S.A.S. is over. Is it the raison?
Certbot failed to authenticate some domains (authenticator: manual). The Certificate Authority reported these problems:
Domain: kolaboratu.int.cines.teledetection.fr
Type: dns
Detail: DNS problem: NXDOMAIN looking up TXT for _acme-challenge.kolaboratu.int.cines.teledetection.fr - check that a DNS record exists for this domain
My web server is (include version):
The operating system my web server runs on is (include version):
My hosting provider, if applicable, is: Our
I can login to a root shell on my machine (yes or no, or I don't know): Yes
I'm using a control panel to manage my site (no, or provide the name and version of the control panel): No
The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): certbot 1.21.0
Note that error is for the apex domain but they are not requesting that name in the cert. All names in the cert were for various levels of subdomains of that. If they don't plan to use the apex name (and it doesn't look like they are), the missing A/AAAA records are expected.
