I have read all of the threads related to this and there are no consistent steps to resolution.

I deleted a domain hosted on one DA server and created it on another. I have pointed the NS records at the domain registrar to the new server and https://dnschecker.org/all-dns-records-of-domain.php shows the changes have propagated for all DNS servers (Google/Cloudflare/Opendns/Authoritative DNS).

The domain was created following the exact same procedures as two other domains which encountered no issues requesting Let's Encrypt wildcard SSL certificates.

I have repeatedly tried to create a wildcard SSL certificate for the new domain and it fails each time with the error message:
Found wildcard domain name and http challenge type, switching to dns-01 validation.
CAA record prevents issuing the certificate: SERVFAIL

When I check to see what the CAA record is, I get this response:
host -t caa foxislandchapel.net.
foxislandchapel.net has no CAA record

dig foxislandchapel.net caa

I have tried suggestions in other posts, including:
./build rewrite_confs
and
./build all
and there does not appear to be anything wrong with the installation.

I have deleted the domain and added it again.

Bottom line is that Let's Encrypt will not issue a cert using the DA panel with the same error message:
Found wildcard domain name and http challenge type, switching to dns-01 validation.

Does anyone know how I can diagnose this issue?
 
What exactly is your hostname? Because I see a faulty PTR record.
164.246.93.38.in-addr.arpa -> fi253.net
this is not an FQDN hostname, so if that is the hostname, both hostname and PTR record are wrong. A hostname must be a FQDN hostname.
So for example server.fi253.net and not a domain name like fi253.net.

So hence my question, what is your hostname?
Believe me, not having an FQDN hostname will give issues at a certain moment either with mail or something else.

Have you tried just creating a new CAA record for the domain?

Seems also it's not propagated fully, there are lots of crosses still here:

Are -all- A records pointing and setup correctly? Did you use DNSSEC?

Here is a similar thread with some solutions which might work.
