title: Why does the /tab is not working when I deployed it to azure?
body: <p>Hi I'm new to teams development. So I created an app and tried it in teams via the localhost:3000, it is working fine.</p>
  <p>But when I deployed the app to my azure the /tab and /config is not working. Do I have a problem in code? deployment? or do I need to configure something in my webserver?</p>
  <p>Edit:
  when I try to go to <a href="http://www.example.com/tab" rel="nofollow noreferrer">www.example.com/tab</a> this is what it returns:</p>
