Hello all,
I received notification that one of my certs was coming up for renewal and just to make sure I ran this:
root@SemMoodle:~# sudo certbot renew
sudo: unable to resolve host SemMoodle
Saving debug log to /var/log/letsencrypt/letsencrypt.log

Attempting to renew cert from /etc/letsencrypt/renewal/www.wls-online.net.conf produced an unexpected error: Failed authorization procedure. www.wls-online.net (tls-sni-01): urn:acme:error:connection :: The server could not connect to the client to verify the domain :: DNS problem: SERVFAIL looking up CAA for wls-online.net. Skipping.
All renewal attempts failed. The following certs could not be renewed:
/etc/letsencrypt/live/www.wls-online.net/fullchain.pem (failure)
1 renew failure(s), 0 parse failure(s)
IMPORTANT NOTES:
-
The following errors were reported by the server:
Domain: www.wls-online.net
Type: connection
Detail: DNS problem: SERVFAIL looking up CAA for wls-online.net
To fix these errors, please make sure that your domain name was
entered correctly and the DNS A record(s) for that domain
contain(s) the right IP address. Additionally, please check that
your computer has a publicly routable IP address and that no
firewalls are preventing the server from communicating with the
client. If you're using the webroot plugin, you should also verify
that you are serving files from the webroot path you provided.
When I look at my DNS host I see that both wls-online.net and www.wls-online.net are pointed to the same IP and have DNS records. What am I missing as to why it is failing?
TIA,
Jeff
