Multisite - New Site - Server Not Found

Task - Convert existing single install to multisite with sub-domain install.

Completed - Fresh Install, Activated Multisite, Imported contents to main site from single install and edited permalink. Now Main site works as expected.

Next - Trying to Create a new site. (site1.example.com)

After adding the new site, url is messed up - site1.example.comnewsitedb

After .com, url has name of the Database as suffix. I'm not sure how to fix this or what went wrong.
