If you have chosen to host your domain's name servers on Cloudflare you need to make sure you set the correct configurations for your domain to work.
After moving my domain to Reactive I'm seeing the error "too many redirects" on my browser. Don't worry that's common since you haven't set up your domain settings correctly.
The error “too many redirects” means that the website keeps being redirected between different addresses in a way that will never complete. Often this is the result of competing redirects, one trying to force HTTPS (SSL) and another redirecting back to HTTP (non-SSL), or between www and non-www forms of the URL.
In that case, all you need to do is go to the SSL/TLS settings of your Cloudflare's admin panel and set your SSL/TLS encryption mode to Full (strict).
Here is a screenshot of how your settings should look after the change:
That's because Reactive provides you with a Free SSL certificate for better security and encryption thus Cloudflare needs a trusted certificate on the server that your domain is resolved. Since Reactive provides you with that certificate the above settings must be set in order for the SSL Handshake to work corretly.
