Thanks for help.
from lego.
Still, I think the issue is not resolved, since none of developers promoted any official solution or fix.
FYI, I'm the main maintainer of lego.
The solution found by Azq2 is in the same direction as my suggestions and fixes his problem, so it becomes the "official" solution.

Hello,
it feels like a propagation issue: clean your TXT records and try again.

Hello,
it feels like a propagation issue: clean your TXT records and try again.
I reproduce this issue even with clean records.
rm -rf ~/.lego # This is important
CLOUDFLARE_API_KEY=.... CLOUDFLARE_EMAIL='my@email' lego --domains 'DOMAIN.COM,*.DOMAIN.COM' --accept-tos --email 'my@email' --dns cloudflare --server 'https://acme-staging-v02.api.letsencrypt.org/directory' run
Important condition - we must don't have a cached challenge for DOMAIN.com (just rm ~/. Lego
)
Otherwise, all works.
I think, the main issue is that LEGO add two records at one time: one for DOMAIN.com and second for *.DOMAIN.com
But both of these records are added to DOMAIN.com

This is expected: having 2 TXT records for the same domain is not a problem.
The problem is the propagation of your TXT records to other DNS servers (the 2 records are not available when LE does the validation).

But anyway this is LEGO's bug. I don't see any problem with this case on acme.sh or certbot.
Maybe, for fixing this issue, LEGO must work like this:
- Get challenge for DOMAIN.com and set to the DNS
- Validate challenge for DOMAIN.com and clean DNS records
- Get challenge for *.DOMAIN.com and set to the DNS
- Validate challenge for *.DOMAIN.com and clean DNS records
- Request certificate
The current behavior is:
- Get challenge for DOMAIN.com and set to the DNS
- Get challenge for *.DOMAIN.com and set to DNS
- Validate challenge for DOMAIN.com and clean DNS records
- Validate challenge for *.DOMAIN.com and clean DNS records
- Request certificate
But failing on 4 or 3 steps.

Hmm, yes, with --dns-timeout 120
seems to be works. Thanks.

Oh no, still not working :(

[DOMAIN.com] acme: error: 403 :: urn:ietf:params:acme:error:unauthorized :: Incorrect TXT record "0QLcNVIyiETrzTkK....." found at _acme-challenge.DOMAIN.com
from lego.
The fact to have multiple TXT records is not a problem, this is why lego handles the DNS challenge for Cloudflare in "parallel" and not sequentially.
This provider has been widely used, for a long time, without any problem with wildcard.
I use it.
The problem is a propagation issue, I don't know why, I will try to find more information but it may be related to your zone or your geographical zone.
from lego.
I reproduce this bug in different geographical zones, different domain zones (.com and .in), different servers (hetzner vs OVH).
This is not environment bug.
Seems like, LEGO use incorrect TXT in cases where more than one TXT present at the same time (because *.DOMAIN.com and DOMAIN.com adds TXT to DOMAIN.com)
Maybe, it is impossible to distinguish which TXT belongs to a specific domain in this case.
But that is my guesses.
Also, requesting certificates only for DOMAIN.com
or only for *.DOMAIN.com
(separate certificates) works fine.
But I want a single certificate with DOMAIN.com
and *.DOMAIN.com
.

Please, see my logs. Or you can check it yourself.

lego uses and adds the right TXT records, the validation is not done by lego but by Let's Encrypt.

It's not how it works. lego uses a "parallel" approach (several TXT records for the same domain) on 90% of the DNS providers without any issues. The other 10% are DNS providers that don't support multiple TXT records for a domain.
It's a propagation issue. There are several possibilities:
- the TTL is too long or too short
- the deletion of the previous TXT records is not propagated fast enough
- the second TXT record is not propagated fast enough
from lego.
Okay, I see you are right. Sorry for the misunderstanding.
I don't see issue with this modifications.

LEGO have any --dnssleep
analog?
--dns-timeout
does not solve this problem.
from lego.
The time.Sleep(60 * time.Second)
is not the right solution:
- waiting 1 minute between 2 challenges is extremely long, this will create a huge regression when a user has to handle thousands of domains.
- you just slow down the challenge requests, it's not related to DNS, so it will be flaky.

This is not suggestion for fix, this is how I check problem, nothing more.
But, I think, option like --dnssleep
(acme.sh, minimum sleep between adding DNS records and validating in LE) should be useful for cases like this.
I can wait a few seconds if it helps avoid DNS issues on LE side.
I didn't find a similar option in LEGO.
from lego.
Hm, I found CLOUDFLARE_POLLING_INTERVAL=30 and it working
from lego.
I experience exactly the same problem with cloudflare. @Azq2, how reliably CLOUDFLARE_POLLING_INTERVAL=30
solution works for you? And how the interval value is chosen?
Still, I think the issue is not resolved, since none of developers promoted any official solution or fix.
