Attempting to expand a new certificate

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g., so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:

I ran this command:sudo certbot --apache -d -d

It produced this output:

You have an existing certificate that contains a portion of the domains you
requested (ref: /etc/letsencrypt/renewal/

It contains these names:

Hi @EsquirolDespert

there is an older check of your domain -

No ip address.

But rechecked now - both domain names are defined:

Host T IP-Address is auth. ∑ Queries ∑ Timeout A Santa Coloma de Gramenet/Catalonia/Spain (ES) - Euskaltel S.A. No Hostname found yes 1 0
AAAA yes A Santa Coloma de Gramenet/Catalonia/Spain (ES) - Euskaltel S.A. No Hostname found yes 1 0
AAAA yes

So you shouldn’t see that error message.

Your zone definition is inconsistent:

Fatal error: Nameservers mit different SOA Serial Numbers

Looks like you have changed your name server definitions in the last minutes.

And that’s

Fatal: Inconsistency between delegation and zone. The set of NS records served by the authoritative name servers must match those proposed for the delegation in the parent zone.: ( Delegation:,,,, Zone:,,

It seems some of your nameservers say is a CNAME pointing to, and some of your nameservers (I think it’s the same ones) say has no A records. The error message would be correct, depending on which nameservers Let’s Encrypt happens to query.

(They also have other problems.)

Thanks both for your answer.
Could be a problem to have and in the same server?
I had before the same problem with but you helped me to fix it. There were a fixed IP pointing to different from current (dynamic). I applied the same solution to and It seems for me it has the same configuration but I’ should be wrong because it is not working.
I have noticed also that in my ISP DNSSEC is not active, nor in neither in; is it this important?

Sorry, any answer about this?

Hi all, could you help me with this, please?

Well, I’ve fixed the problem. My DNS provider has two groups of DNS, one for Dynamic DNS and another for Static DNS. So it is not possible to point the domain to DNS from both groups. You have to chose. Now both domains are working properly and renewing their certificates without problems. pointing to static DNS and pointing to dynamic DNS.
