Suddently can't rewnew cert on apache

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. crt.sh | 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: brainlint.org

I ran this command: tried several but most recently "certbot -v renew"

It produced this output:
Domain: brainlint.org
Type: caa
Detail: CAA record for brainlint.org prevents issuance

Domain: www.brainlint.org
Type: caa
Detail: CAA record for www.brainlint.org prevents issuance

My web server is (include version):
Server version: Apache/2.4.38 (Raspbian)
Server built: 2020-08-25T20:08:29

The operating system my web server runs on is (include version):
Raspbian 10

My hosting provider, if applicable, is:

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): 1.17.0

I set this up in may, it worked fine, dry run worked like a charm. I haven't touched anything since then and am unsure why I can't auto renew. I AM able to access the site securely right now, certbot just won't renew.

Thanks!

Hmm: https://unboundtest.com/m/CAA/brainlint.org/HY6Y5KET

That's meant to be

issue "letsencrypt.org"

not

letsencrypt.org "issue"

The tag and the value appear to have their places switched.

Good grief, that was it... thank you. Why in the World did it work the first time like that?
