It's an Angular application, I could see a GET call in Doc filter under the Network tab(refer image), [Network call screenshot]1 the call name is same as the router URL. While running in local host it returns the code index html file with 200 status however when the build is pushed to UAT, it returns 404 and not a blocker. In production, it returns same as 404 error status code but after the application is not running. What this call means and how could resolve in UAT and Prod. Below is the build command for UAT,

ng build --configuration=uat3  --base-href /XXXX/ --output-path=dist/UAT/public
