Hi all - So I just ran into the changes lately from letsencrpt.
certbot-auto is no longer available.

I added this to httpd.conf
<VirtualHost *:80>
ServerName mydomain
</VirtualHost>

service httpd restart

When I do "certbot -d mydomain" I get this :
   Domain: mydomain
   Type:   unauthorized
   Detail: Invalid response from

http://mydomain/.well-known/acme-challenge/i_fU1bFrQZzgfVI2FtWo8Ov0ITjplCcPjXdK61Fwa-w

What did I miss ?
Thanks
