Was there some dns lookup failure in recent days?

And... nobody changed nothing !
[yes, I'm a conspiracy theorist]


From the next certificate which was attempted this weekend:

2022/12/17 04:11:05 [INFO] Skipping deactivating of valid auth: https://acme-v02.api.letsencrypt.org/acme/authz-v3/187639913467\n

2022/12/17 04:11:06 error: one or more domains had a problem:\n
[*.fes.sys11cloud.net] acme: error: 400 :: urn:ietf:params:acme:error:dns :: DNS problem: SERVFAIL looking up TXT for _acme-challenge.fes.sys11cloud.net - the domain's nameservers may be malfunctioning"

It needed 4 challenges. 3 of them succeeded, one failed (you can see that from the 4 auth links), blaming the name servers. However it is the same name servers in all cases. A few retries later, the 4th challenge succeeded too.

In other words: unless the error messages get made much clearer, proving exactly which name server is failing, I really don't see how the problem is on our side.

Sorry for insisting on that. Please fix the DNS first.
