Sample vhost configuration:

<VirtualHost *:80>
ServerName dos.archive.computer

ServerAdmin webmaster@localhost

ProxyPreserveHost On
DocumentRoot /var/www/html/dos.archive.computer
ProxyPass /.well-known !
ProxyPass / http://10.0.3.10/
ProxyPassReverse / http://10.0.3.10/

ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined

#The below lines are just for auto-redirecting to https

RewriteEngine on
RewriteCond %{SERVER_NAME} =dos.archive.computer
RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]

</VirtualHost>

Create .well-known folder

wget https://dl.eff.org/certbot-auto

chmod a+x ./certbot-auto

./certbot-auto

setup crontab with the follwing:

30 2 * * 1 /usr/local/sbin/certbot-auto renew >> /var/log/letsencrypt-renew.log

Above line really depends on where you installed certbot-auto – sometimes it will be in the root home directory if thats where you did the wget to.
