Phantom DNS TXT record conflict with certbot

Hi everyone! I want to configure a web server working with SSL and use certbot. A DNS TXT record is needed to setup certbot. When I do a DNS lookup of my domain (prodesk.freeboxos.fr) I see that there’s already an existing TXT value (MBVDYOa1bMCVSAgKBiiw-8NOnygaNSL5ncdnPKM2iLI) that is not in my Cloudflare DNS manager. I need to delete it to finish my certbot setup, what can I do? If needed, i can link the script of my certbot setup showing an error or give more details.

Your domain isn't using Cloudflare Nameservers

That record is coming from those freens nameservers, if you mean to use Cloudflare you'll have to change your nameservers at your registrar first

I forgot to say that the domain «name » used to work with certbot is this one: _acme-challenge.prodesk.freeboxos.fr. Does this change anything?

no, the entirety of your domain freeboxos.fr is not using Cloudflare. Maybe it was back then and you/something changed it? Cloudflare is not authoritive for your domain, and no changes you make in Cloudflare would matter for Queries. If you go to the overview of your website in Cloudflare, it should tell you to set up your nameservers/that your site is inactive According to whois, the last update to your domain was like ~30 days ago last-update: 2023-08-16T03:19:29.108179Z Perhaps that's when your nameservers got switched
