I cannot renew Certificate

Help

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:nblp.moph.go.th

I ran this command: sudo certbot --apache

It produced this output:
Saving debug log to /var/log/letsencrypt/letsencrypt.log
Plugins selected: Authenticator apache, Installer apache

Which names would you like to activate HTTPS for?

1: nblp.moph.go.th

Hello @chit164, welcome to the Let's Encrypt community. :slightly_smiling_face:

You need to add letsencrypt.org to your DNS CAA record or remove the CAA record altogether.
