DNS problem: NXDOMAIN looking up for _acme-challenge

Hi. I’m trying to set a wildcard certificate for the domain *.lookmonsite.fr
My domain is hosting by OVH.

I ran this command :
letsencrypt certonly --manual --preferred-challenges dns --register -d *.lookmonsite.fr

Then, I’ve added a new TXT record using the OVH panel :

And when I’m validating the certificate, here the error :

DNS problem: NXDOMAIN looking up TXT for _acme-challenge.lookmonsite.fr


    • The following errors were reported by the server:*
  • Domain: lookmonsite.fr*

  • Type: None*

  • Detail: DNS problem: NXDOMAIN looking up TXT for*

  • _acme-challenge.lookmonsite.fr*

What should I do ?

Thank you

Your domain’s nameservers don’t contain that DNS record, so it looks like it was not added correctly.

Could you please take a screenshot of the user interface where you added the TXT record?

Thanks. Here is the record :

Something has gone wrong with the upload of the screenshot. I don’t think it’s your fault. Could you try upload it to imgur.com or somewhere like that for now?

I’ve edited my previous post.


In the Domaine column, you must put _acme-challenge.lookmonsite.fr. .

In the Cible column, you must put just GgASZeC8XitdIOrdsawPdj8dKyBtDPDou7OwLW9wECs .
