Cannot add domain to Cloudflare

Hello

Am trying to add my domain defisport.mu to Cloudflare but am having this error:

Failed to lookup registrar and hosting information of defisport.mu at this time. Please contact Cloudflare Support or try again later. (Code: 1110)

Can anyone please help?

Thank you.
