Hello

I’m trying to install Wildcard SSL Certficat from Virtualmin Dashbord.
And even if, when I try it on SSH Terminal, by launching the following certbot command:

certbot certonly --manual --preferred-challenges=dns --email admin@ourdomain.com --server https://acme-v02.api.letsencrypt.org/directory --agree-tos -d ourdomain.com -d *.ourdomain.com

I get the following error:

Press Enter to Continue
Waiting for verification…
Challenge failed for domain ourdomain.com
dns-01 challenge for ourdomain.com
Cleaning up challenges
Some challenges have failed.

IMPORTANT NOTES:

• The following errors were reported by the server:

  Domain: ourdomain.com
  Type: unauthorized
  Detail: No TXT record found at _acme-challenge.ourdomain.com

  To fix these errors, please make sure that your domain name was
  entered correctly and the DNS A/AAAA record(s) for that domain
  contain(s) the right IP address.
