Unable to register new domain SOS

Hello,

I've been trying to register to Zoho Mail free application and unable to, my domain name is conuko . com and everytime i put the name on your signup website it shows me the error message "This domain is not supported or is already registered with zoho"

Please reset or remove the domain as this is a brand new domain i own and would like to use your services with it. I can prove ownsership by adding any CNAME or uploading a txt file or any other method, please let me know

* This Domain is not supported or is already registered with Zoho
