Two pages to sign up for an email account that do not work

Unable to sign up for email

When trying to create account at https://www.zoho.com/signup.html

If fails with "We are unable to process your request now. Please try again after sometime or contact support@zohoaccounts.com"  appearing in red
a similar topic mentions virus...  Im on a 4 week old fresh install of Win10 full Norton and malwarebytes
on personal internet connection.
 any ideas?
been like this for 3 days

So I then tried this page

entered first and last name chose an email address  ( @zoho.com)
united kingdom
accepted terms and conditions
clicked sign up

get another another message in red "The zoho.com domain cannot be used to sign up. Please use a different email address. Learn why?"

The learn why page states to got to: https://www.zoho.com/mail/ 

however on that sign up page  you have to enter you mobile phone number when signing up

so why does the page https://accounts.zoho.com/register   even exit if it carnt be used?

i like Zoho because its big on privacy, my mobile number is private.
