I'm trying to re add this domain and the message failed to details pops out. Domain not new

I’m trying to re add the domain barcelonahits.ml and this message pops out :Failed to lookup registrar and hosting information of barcelonahits.ml at this time. Please contact Cloudflare Support or try again later.
Other .ml domains are working for except this one. Help??

That domain is registered under a TLD which is governed by the Freenom registry. Freenom currently experiences issues with their Whois service which prevents such domains from being added to Cloudflare. Freenom needs to fix that on their side.

Unfortunately there is no ETA known for that.

It probably is best to register a proper domain instead. They already go for less than $10 a year.

But i’ve anither 2 domains added to cloudfare using freenom and no problem has energed
