For SSL, add the follow to your vHost config
Redirect to https:// - insert in virtualhost:80
        RewriteEngine   On
        RewriteCond     %{HTTPS} !=on
        RewriteRule     ^/?(.*) https://%{SERVER_NAME}/$1 [R,L]
Add virtualhost:433 with the same basic attributes as :80. Add the following
        SSLEngine On
        SSLCertificateFile /etc/letsencrypt/live/lunetikk.de/fullchain.pem
        SSLCertificateKeyFile /etc/letsencrypt/live/lunetikk.de/privkey.pem
