SMART on FHIR well-known configuration returning 403, but listed as unauthenticated in MP

So I have been working in Healthcare Interops for about a month now and in IRIS. I am looking to implement SMART on FHIR and I am currently working to make an endpoint that works as the discovery endpoint. It is a custom dispatch class and unauthenticated is selected for access. I am trying to make a simple get request from Postman to test that the proper JSON is sent, but I receive a 403 Forbidden error. It is reaching IRIS it seems so I know its not a reverse proxy error. Here is an example of my custom Dispatch Class. Then also there is a screenshot of my web application I made specifically for the discovery endpoint. I have read some mentioning roles regarding unknown users and some mention about headers but nothing seems to get passed the 403 error.
