Error: 403 Client Error when using EPIC FHIR Prod

So I was able to get sandbox data and pull it just fine. Now moving from sandbox to production, I been a patient at Methodist and am using my personal crediential against their API. And I am getting authetication error. Nothing changed in my code from Sandbox to Prod so not sure why I am getting error. The endpoint that I am trying to hit. https://epicproxy.et0922.epichosted.com/FHIRProxy/api/FHIR/R4

}

Also I have two apps why isnt client ID showing up on second app it says Client Ids for this app will NOT be automatically donwloaded to customer systems upon marking it ready for production. But my other App doesnt have that and shows keys [APP Key] (https://i.sstatic.net/9QRxtuCK.png) [Notice] (https://i.sstatic.net/4axtN0AL.png)

API pulls data, sandbox worked
