Problem with transferring cloudflare dns on .it domain

Hi guys, the registrar Aruba says me that the cloudflare dns are not valid for .it domains …
He advise me to validate the dns on (dns_ check_nic_it) but the validation is never successful.
How can I proceed?

Actually I use this DNS
norm.ns.cloudflare.com 173.245.59.134
mia.ns.cloudflare.com 173.245.58.200

Many thanks,
Giuseppe
