title: Cors-anywhere not working in chrome in production of Angular app
body: <p>I've tried to use newsapi to build and host a website. I've used angular 6 and for hosting I've used firebase. When i get response using httpclient I was getting CORS issue which I've resolved using <a href="https://cors-anywhere.herokuapp.com" rel="nofollow noreferrer">https://cors-anywhere.herokuapp.com</a>. It is working fine in all browsers except chrome. It's giving proper response in firefox, but not in chrome.</p>
  
  <p>I'm getting the following error:</p>
  
  <p>Yi {headers: Vi, status: 426, statusText: "Upgrade Required", url: "<a href="https://cors-anywhere.herokuapp.com/https://newsap" rel="nofollow noreferrer">https://cors-anywhere.herokuapp.com/https://newsap</a>…020-06-03&amp;apiKey=*******************", ok: false, …}</p>
