Hello
I am aware that there are other posts on this issue, tried all the remedies suggested but none worked for me.
I have a server running Ubuntu 16.04.02 LTS with VESTACP and installed letsencrypt-vesta following this guide here on apache2.
When I run this code letsencrypt-vesta admin example.com (example.com replaces a real domain name) I get the following error
root@server:~# letsencrypt-vesta admin example.com Saving debug log to /var/log/letsencrypt/letsencrypt.log Obtaining a new certificate Performing the following challenges: http-01 challenge for example.com http-01 challenge for www.example.com Using the webroot path /etc/letsencrypt/webroot for all unmatched domains.

Let's Encrypt returned an error status. Aborting. root@server:~#
DNS A record is properly set to direct to the server’s fixed public ip address.
How can I fix this error.
