ngsw-worker.js not registered on server when deployed

Angular Application with .net core web api using PWA for offline purposes .But when I deploy the application to server , I am not able to see PWA instances in Server Worker in the browser . . If I run it locally and do http-server it loads everything and works fine on local for PWA. i can't share my screen but I can send you screen shots of appropriate files. I also have similiar project so I can send it to you , you can deploy it and try to solve it on your end
