Hi @WarOrg,
Thank you for your message, and welcome to deSEC! 
This happens when your update request contains a domain name that is not in your account.
Hope that helps!
Stay secure,

Hi Peter,
It certainly did have a miss-matched domain name. Teaches me to triple check my work more often. Thanks for the help!
