Looks like the DNS propagation process is still ongoing and NXDOMAIN issue
Could you check if you’ve got the correct Cloudflare nameservers set at your domain registrar (https://www.spaceship.com/), which are assigned for your Cloudflare account?
When you go to Cloudflare dashboard and select your Website, are they the byorn and donna or some other?
Furthermore, in the meantime could you please double-check the DNS tab of Cloudflare dashboard for your zone if you’ve got DNS records in-place or some are missing?
Looks like you don’t have neither A lamodelgurlof.eu neither A www pointed to your web hosting server IP address.
Could be the automatic scan failed during the process of adding your Website to your Cloudflare account.
please contact your registrar for any information on why your domain is not working currently.
The domain does not currently exist in the parent nameservers, and no one except for your registrar can help you with that:
