title: 404 error while accessing token service of Azure B2C
body: <p>I am trying to call the rest service for getting idToken from Azure B2C application using following URL:</p>
  <pre><code>https://login.microsoftonline.com/{tenant}/oauth2/v2.0/token?p={POLICY}
  </code></pre>
  <p>I am passing all the required parameters in the payload :</p>
  <pre><code>grant_type=authorization_code&amp;client_id={ClientID}&amp;scope=https://{tenant}.onmicrosoft.com/api/read openid offline_access&amp;code={AUTH_CODE}&amp;redirect_uri={REDIRECT_URI}&amp;client_secret={CLIENT_KEY}
  </code></pre>
  <p>The same approach is working on one environment but returns
  404 : The resource you are looking for might have been removed, had its name changed, or is temporarily unavailable.</p>
  <p>when accessing from another environment.</p>
  <p>What am I missing here? Any Azure configuration that I need to check?</p>
