title: angular based PWA does not work on Google cloud platform but works on firebase
body: <p>I am new to pwa and google cloud. I am trying to create and host simple pwa on the web. so far I have hosted it on firebase <a href="https://pwademo-cba43.firebaseapp.com/" rel="nofollow noreferrer">https://pwademo-cba43.firebaseapp.com/</a>  . on firebase PWA is installable and the service work is also detected. but the problem arises when I host it on google cloud. it does not even detect service worker and also does not point to start URL. is there any proper tutorial available to make it work?</p>
  
  <p>tried changing the start URL. created service worker again</p>
