I have installed CraftCMS on an Arcustech VPS and successfully added a domain name. Using the domain without the shared SSL works without any problems (e.g. www.example.com / example.com). However after adding the Cloudflare shared SSL certificate and using the "Flexible" configuration option, the website returns Error 521 Web server is down.

I have configured the domain in the CraftCMS CP to contain https and added the following to my .htaccess file:

# SSL only
RewriteEngine On
RewriteCond %{HTTP:X-Forwarded-Proto} !^https
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}

Am I missing a crucial step to get the SSL working?
