Not an active zone

When transferring my domain from namecheap, an issue has occurred.

My domain is stuck on zone not active.
I read that i have to change my nameservers, however, the domain is no longer shown at Namecheap.

Furthermore, not only is that an issue, but the whole website is down, and i don’t have access to configure anything!

Furthermore, on whois info it shows that the website is registered with:
WHOIS Server: http://whois.Cloudflare.com
Registrar: Cloudflare, Inc

What is the domain?
