I’m trying to set up letsencrypt on a Nginx server, running on CentOS 7.
The web server is working on http.
My domain is: mirai.klo.pe
I ran this command: certbot --nginx -d mirai.klo.pe --staging
It produced this output: Error getting validation data
My web server is (include version): nginx 1.12.2
The operating system my web server runs on is (include version): CentOS 7.4.1708
My hosting provider, if applicable, is: Digital Ocean
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
