hi @kantans,

After `npm run start`, did you open [https://localhost:9999](https://localhost:9999/) in your browser?

Hey @kantans,

Did you run `npm install` in sample-app-web-master\CDN?

> Hey @tony, I just tried and it worked. Can you try following these exact steps as I did and let me know if it works for you. In terminal: git clone https://github.com/zoom/sample-app-web.git cd sample-app-web/CDN npm install npm run start You should see this If this does not work, can you send me a link to your code on github and I will try to debug. Thanks, Tommy

Let me know if that helps!
