Annoying problem with LetsEncrypt when running
IMPORTANT NOTES: - The following errors were reported by the server: Domain: test.example.com.au Type: connection Detail: DNS problem: query timed out looking up CAA for test.example.com.au 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.
For some reason if you try and renew a cert with two domains in it you get the annoying error above. So try this:
./certbot-auto certonly --webroot -w /var/www/test/ -d test.example.com.au
