Letsencrypt with cloudflare

1

Hi

I’m trying to switch over to cloudflare with letsencrypt and DNS verification.

I’ve disabled the duckdns and configured the letsencrypt according the documentation.

When starting letsencrypt, i can see the TXT getting added in my dns config and removes after a few minutes, however i’m getting this error in the log:

s6-rc: info: service s6rc-oneshot-runner: starting

Certbot failed to authenticate some domains (authenticator: dns-cloudflare). The Certificate Authority reported these problems:
Domain: ha.REDACTED.com

Detail: DNS problem: looking up TXT for _acme-challenge.ha.REDACTED.com: DNSSEC: DNSKEY Missing

Hint: The Certificate Authority failed to verify the DNS TXT records created by --dns-cloudflare. Ensure the above domains are hosted by this DNS provider, or try increasing --dns-cloudflare-propagation-seconds (currently 60 seconds).

Don’t know what i’m doing wrong here, as i can’t seem to find what the root cause actually is…

anybody can point me out to something?

As I remember you have to use dns from cloudflare to make this work. It could take up to 24 hours to propagate. It was something like that.

Hi thx for the quick answer, cloudflare is not my registrar, i thought it was enough to set CF as my nameservers and add the domain there. I can see all my dns records in CF. Do i need to move my DNS to CF so it’s CF that is the registrar?

As I remember you have to move your dns records to cloudflare. There is doc somewhere online so check it out.

Hi, just transfered my domain to Cloudflare, and it works like a charm now.

So basically a pre-req of this is to have your DNS transferred to clouflare. At least that’s my conclusion, and for 10$ it’s even less than my current registrar…
