I think it is worth noting that you are on a very old version of NIOS. Per the Deployment Guide, you need to be at 8.2 at a minimum. You also need the Security Ecosystem License which is not supported in that version.

From the Guide requirements:

Infoblox:

1. NIOS 8.2 or higher

2. Security Ecosystem License

3. Outbound API integration templates

4. Prerequisites for the templates (e.g. configured and set extensible attributes)
