I am trying to install SSL cert by following this page https://www.vultr.com/docs/setup-letsencrypt-on-linux
All goes well until I try to install the actual certificate, I get the following errors
Error while running apache2ctl graceful.
httpd not running, trying to start
Action 'graceful' failed.
The Apache error log may have more information.
