I have my custom server with my own nameserver. I am able to point my two domains there but one of my client is not able to point nameservers on that server. Its automatically get set default nameserver back. all difference is his domain are with com.eu extension and mine are .com. He have got email from godaddy that we can not make changes, object not found. I am unable to know what is issue and how I can solve it. Let me know if someone can help for achieve the goal.
