Website activation

I activated my site on Cloudflare and changed the name servers over 24 hours ago. Still, the site isn’t up and running.

What is the domain?

You actually have not changed the nameservers at your registrar, which is required to activate your domain in Cloudflare. You instead added your Cloudflare nameservers into the zone hosted at your existing DNS provider. You must visit your domain registrar and remove any nameservers other than the two assigned in your Cloudflare account. You currently only have rzone.de nameservers set at your domain registrar. See the following for details:
