404 Not Found API Endpoint

Hi xenForo Community,

Hopefully this is the right section, I apologise if this isn't.

Currently have an issue with the API Endpoint, here's the server details:

xenForo: v2.1.10 Patch 2
PHP: 7.4.9
MySQL: 10.3.23-MariaDB
Web: nginx/1.19.1

I've followed:
https://xenforo.com/community/resources/how-to-call-the-xenforo-api.7875/
https://xenforo.com/xf2-docs/dev/rest-api/

For now, through Postman I've set it up as...
