I have installed ansible tower on CentOS 7. I am getting error message while I am creating host or group. Please advice.

Ansible Version : **ansible 2.4.0.0**

CentOS : **CentOS Linux release 7.4.1708 (Core)**

Error message when creating group : **Call to /api/v2/Groups/ .Get returned: 500 A server error has occurred.**

Error message when creating host: **Call to /api/v2/hosts/ .Get returned: 500 A server error has occurred.**

**Please see below screen shots**
