Letsencrypt does not find A records for my domain, DNSSEC issue?

Hi all,

Im running a couple of virtual hosts on my droplet. I have secured 1 of them successfully with letsencrypt. When I try to secure a second one I run into trouble, I get the following error:

 - The following errors were reported by the server:

   Type:   None
   Detail: DNS problem: SERVFAIL looking up A for

Also when running letsdebug I get DNS lookup errors. ( I’ve configured both domains with the same DNS entries. The first domain works but this one doesn’t.

This is my DNS zone as set up in digital ocean control panel:

$TTL 1800 IN SOA 1572985497 10800 3600 604800 1800 1800 IN NS 1800 IN NS 1800 IN NS 3600 IN A 43200 IN CNAME 3600 IN CAA 0 issuewild ""

The website runs successfully under HTTP, and is reachable.

WHOIS lookup does show that the nameservers are successfully set to digital ocean:

I did some DNSSEC checks and I see some errors, but I have no idea what they mean how to resolve them:

Any suggestions are very welcome.

It looks like that the domain name that you have problems with is picking up the SSL certificate of the other domain name. As your DNS zone seems correct, would you mind sharing your Apache Vhost files for the two domains?
