I am unable to create certificates using the DNS Cloudflare validation on certbot/letsencrypt. I have a domain rosalyn.ovh from the OVH provided transferred to Cloudflare (changing the DNS servers). Everything works except asking for certificates using DNS validation.
From the cloudfare dashboard I can see that _acme-challenge TXT records are added correctly but letsencrypt complains that the Certified Authority cannot find them.
Digging further it seems as if there are multiple stale _acme-challenge TXT records on the domain (they do not appear in the dashboard) I can check them with:
dig _acme-challenge.rosalyn.ovh TXT
How can I delete such records from my domain? Why are they not shown in the cloudfare dashboard?
Thanks in advance!
