domain mapping for newly registered domain not working

i have a registrered a domain (umashankar99.com) and have been trying to map the domain to the blog http://umashankar99.webkuteer.biz

and the same is the case is with myco999.com mapped to >>> http://myco999.webkuteer.biz

but i keep getting the error "Domain Name is unavailable to access"

I have followed the following steps
1) the domain has been parked on webkuteer.biz
2) the domains are pointing to the dedicated ip 162.222.226.196 and to the home page of the website webkuteer.biz
3) i have not redirected it to any other website in the cpanel of webkuteer.biz
4) i used whatsimydns.net to check that the domain is completely propagated to the ip address

I have some other domains which are pointing perfectly to their respective subdomains of webkuteer.biz (mohith2015.com or naveen99.com)

Please advise where i might have gone wrong.

I am attaching the screen shot of the error message for your information

best regards
