Why my website not opening on certain devices whereas working fine on others? [closed]

I recently built a website namely crikick.com ... I have already bought a domain, a server, and a web hosting service from bigrock.com, but now the website is not opening in few devices and showing the following-

This site can't be reached

www.crikick.com's server IP address could not
be found.

DNS_PROBE_FINISHED_NXDOMAIN

The main concern is that I didn't made any change to DNS recently, and it is opening and working fine on other devices, I have recently made certain changes in my CSS properties and updated the CSS file in cpanel, after which the problem came in my personal phone and few others but not each and every phone...

Kindly tell that whether it is just for certain time or I need to do certain things for get this going !!!
Please Help
Thanks in advance for the answers...
