I cannot create new account on my WHM. Need help urgently.

Hello, I cannot create new account on my WHM. Need help urgently. When I'm trying to create a new account for my website techmoot.com , I have got this following massage. "Account Creation Status: failed (XID eqmsjy) A DNS entry for “techmoot.com” already exists. You must remove this DNS entry from all servers in the DNS cluster to proceed." Now what can I do?
