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.
My web server is (include version):
nginx version: openresty/1.11.2.2
The operating system my web server runs on is (include version):
ubuntu-14.04
I am a newbie here…really really thanks if you could help
thank you very much. I ran the command on my computer and the webserver is another one. the document on the official website didn’t mention things like this we need to give particular attention…e…maybe I didn’t see it
anyway thank you very much
and now I am trying another command on the webserver：
certbot certonly --webroot -w /var/www/example -d example.com -d www.example.com
Maybe @SwartzCr, who has been dealing with documentation updates, can look into how to make clearer that Certbot is meant to be run directly on the web server (which has been an occasional problem for a number of users).
When you ran your newly updated command on the server, did you succeed or get any error message?
The commands you mention talk to the apache server / filepath and modify them. If you are not running them on your web server then when the Let’s Encrypt servers try to validate you own the domain they will fail
