How can we reproduce this behavior?
Is there a way to capture debug info from the plugin? (I already have DEBUG in the global section of my Caddyfile)
If I delete the currently downloaded certificate and restart Caddy, will it download a new certificate so we can then look over the logs?

Hm, I don't think we emit debug logs in this plugin currently (because of how simple the code is and the fact that most info that is needed comes back as errors). But the most helpful logs would be the ones that come before the 1 log line you posted here.

Yes, but make sure to switch to your CA's staging endpoint (if there is one) first, otherwise you'll get rate limited quickly.
Logs are good, but even better is how can we reproduce the problem?

@BDaddyG I tried to replicate your issue. Everything seems to work fine.
Also, by looking closely at the Cloudflare audit log, I can see that the "acme-challenge TXT record" is created and then deleted as expected.
Not sure how yours didn't

Here is the complete log with the error (I had stopped Caddy after I saw it had obtained a cert):

I'll delete the current certificate and have Caddy get a new one today and see what happens. Maybe it was a glitch at Cloudflare's end?
Thanks for looking at the issue!
I was able to delete the current certificate and have Caddy get a new one... and the TXT record at Cloudflare was removed.
I tried a couple of times and things worked correctly each time.
So, it appears it was a glitch on Cloudflare's end.
Thanks for your time and thoughts about what could be going on.
Context canceled usually means something took too long, so if the network or the remote service was delayed signifcantly, that could cause the problem, and those are usually intermittent.
Although, looking at your logs, it looks like Caddy was stopped right then, which is another thing that can cancel the context prematurely.
(I had stopped Caddy after I saw it had obtained a cert)
Aye, that would do it, since it was still cleaning up. Just leave Caddy running, it will keep the cert renewed.
Hi! It seems that for me is the same. TXT records are not being removed (I can't confirm more than I see multiple TXT records for the same domain). I just switched from systemd to docker, but anyway how it should detect if a TXT record should be removed? Does it remove all TXT records for a given domain when renewing certificate? What happens with domains which are removed from caddy? Does caddy keep a track of deleted domains?
It's provider-dependent, but in the case of Cloudflare's API, DNS records have an associated ID, and we use IDs to remove the specific record that was created. In order to retrieve the ID, though, we first "get" the records from the API that match the type and name.
Hello
Just started working with Caddy, and with the Cloudflare plugin.
I was able to get the setup correct in that: the _acme-challenge TXT record is created, and a SSL cert is obtained.
But the plugin is not able to remove the _acme-challenge TXT record.
The log reports:
I've verified that the API Token used is set to:
which should be OK, since the challenge record was created, right?
Any pointer as to where to look?
Specs: custom build of Caddy v2.4.5 with the Cloudflare DNS plugin downloaded from the Caddy site. Ubuntu 20.04 Server Caddy installed from the PPA, then the caddy executable overwritten with the custom build Caddy running as a service
Thanks!
