DNS problem: SERVFAIL looking up CAA for ga

[Magnus]

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. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:

www.magnusbrzenk.ga

I ran this command:

sudo certbot --apache

It produced this output:

IMPORTANT NOTES:
 - The following errors were reported by the server:

   Domain: www.magnusbrzenk.ga
   Type:   None
   Detail: DNS problem: SERVFAIL looking up CAA for ga

My web server is (include version):

Apache/2.4.29 (Ubuntu)

The operating system my web server runs on is (include version):

Ubuntu 18.04

My hosting provider, if applicable, is:

AWS Lightsail

I can login to a root shell on my machine (yes or no, or I don’t know):

Yes

I’m using a control panel to manage my site (no, or provide the name and version of the control panel):

No

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you’re using Certbot):

certbot 0.31.0

Also:

I figured I'd give AWS lightsail a trial, so I redirected a free domain I set up 
(magnusbrzenk.ga) from a preivous target to a new target on AWS lightsail. 
Certbot worked fine with this domain with the previous target, but now it keeps failing with
`DNS problem: SERVFAIL looking up CAA for ga`. Any ideas what this is all about?

It looks like the registry operator for the ga TLD (Freenom?) is having some issues. I can reproduce your issue with a different domain of mine (acmedev.ga).

Until they fix their nameservers, there is one workaround available to you, and that’s to create your own CAA record:

magnusbrzenk.ga. 360 IN      CAA     0 issue "letsencrypt.org"

OK, thanks for the info. Doesn’t look like freenom will let me create CAA records. I’ll check back in a day or two.

[Magnus]

OK, it’s working now
