Cannot update nameservers

I am trying to update the nameservers of my domain to point to Godaddy and I get the following error: One or more of the nameservers you entered cannot be verified as an accurate nameserver. Please double check your entry, and if you have any questions contact the registrar to which you are attempting to direct your domain. 

All I am doing is using the default Godaddy nameserver address of ns1.godaddy.com and ns2.godaddy.com for the primary and secondary fields.
