I have a simple website with domain www.planetapp.duckdns.org.
I would try to install let's encrypt SSL certificate but it return the error "Could not execute your request - CAA record prevents issuing the certificate: SERVFAIL".
Anyone have had this problem?
I have seen a lot of threads but I can't find any solution.
 
Sorry but I'm new in this world and I have to study a lot of things in dns ecc.
My website was previously hosted on a website with Plesk pannel and I clicked on "generate ssl let's encrypt certificate" and it works correcly so my website was https and not http.
Why this time don't work like Plesk?
 
I have not set any AAA record, because i'm using duckdns.org so I changed only record A to point to my new hosting server with Directadmin
 

TLS Certificate expiration​

The certificate expires February 18, 2023 (365 days from today)

Huh ? LE only provides 90 days right?, where is this coming from ?
You have problem with the nameservers, I can't check your domain for dns errors !
Try your self intodns.com
 
Might be a DNSSEC issue. Could you try either disabling DNSSEC on your domain zone or adding the following CAA record?

Code:
planetapp.duckdns.org. CAA 0 issue "letsencrypt.org"
 
I have solved the problem.
The problem is related to duckdns.
Duckdns is a free dynamic DNS service that allows you to point a subdomain under duckdns.org but you can't add zone or CAA record.
I solved buying a domain and pointing to my vps with record A
Thanks Active8 and wtptrs, you are very expert in this sector.
 
If you are using a CAA record please be sure you have the feature on.

Code:
cd /usr/local/directadmin
./directadmin set dns_caa 1
service directadmin restart
 
Using duckdns.org the problem persist.
Try yourself to create a record with a duckdns.org and point to a VPS.
It doesn't work

Not sure if this was for me. I was merely pointing out if you are wanting to use CAA records in DA you need to turn on the feature.

I would not use Dynamic dns features personally. DA has it own DNS system installed already.

for sure the way to go.

Odd... then duckdns is one of the few which prevents it.
I got a subdoman on dhs.org and other dynamic DNS services and don't have issues creating a letsencrypt certificate.
