Domain Mapping is redirecting site to primary site

I have a domain ( that I am trying map to a subsite ( I have checked, recheck the DNS record a dozen times. When I mapped the domain to the subsite and set the domain mapping settings to front end should direct to map domain, the site is redirecting to the primary domain (

Everything in godaddy is pointing to ip address of the dedicated ip I also added the domain to the primary domain in cpanel. My other domains that are mapped to other subsites are working fine, not sure what's going on.
