Unable to Create a new Zoho mail account

Good Day,

A friend of mine is in the process of setting up the free version of zoho mail. They currently own the csmsj.co domain and when they try to, they get the message We are unable to process your request now. Please try again after sometime or contact support@zohoaccounts.co"



Could you please assist.?

Thanks in advance,
Brian Hall
