I have a fresh multisite install and cannot get the mapped domains to work. I have WP 3.9.1 and Domain Mapping 220.127.116.11. I have a VPS (Hepsia control panel) with a dedicated IP for the network domain. The mapped domain is propagated to the correct IP. Sunrise.php is in the correct folder. I even downgraded to Domain Mapping 4.1.2. The subdomains are working perfectly. When I try to map a domain, the Health status is invalid.
