How To Deploy Angular 7 with Net Core API Separately on Azure

Right now I have a .Net Core Application with Angular 7 as the Client

I have both the API and Client deployed on Azure however I am stuck on how to get the client working on azure where it reaches the .Net Core endpoints. On my login post request I am getting a 404 however it works on my local build... I'm not sure exaclty what I'm doing wrong?

    Request Method: POST
Status Code: 404 Not Found
Referrer Policy: no-referrer-when-downgrade
