Please see the PINNED post in the user comments below ... it is some help from one of the developers on the Vestacp team. See below "Dpeca".
(first you need to login as root to your server, down below you need to replace yourdomain.com with yours, you can read more about the script below here: [ Ссылка ])
Here are the three (3) commands you need to execute in order:
wget [ Ссылка ] -O /usr/local/bin/generate_ssl
chmod u+x /usr/local/bin/generate_ssl
generate_ssl admin Yourdomain.com
This video will show you how to install a free SSL certificate (using Letsencrypt) on the Vestacp control panel domain or subdomain itself. I will be using Ubuntu linux 14.04 as the operating system but it works the same on 16.04. This way you can access the control panel over https and not http. #vesta #vestacp #ssl #certificate #install
