Why are my sites that have a domain mapped to them not resolving to WordPress?

Websites that only use the sub-domain are accessible. This only affects sites with mapped domains.
Ex:
chattasug.livelocalfirst.com works
jimmytlive.livelocalfirst.com does not work
- jimmytlive has a domain mapped to it that is jimmytlive.biz

This issue arised after migration to a new host.
Changed the IPs to the new Dedicated IP we have for livelocalfirst.com as well.
