The authorization can run into trouble under the following scenarios:

  1. When you are trying to authorize from your custom/vanity URL. Please try the authorization after logging into your Account using Freshdesk URL, which would go by YourCompanyName.freshdesk.com.
  2. If you have SSO enabled, please try logging in using your Freshdesk credentials after bypassing your SSO, using the URL - YourCompanyName.freshdesk.com/login/normal.
  3. Please ensure if you are not logged into another Facebook account on your browser at the same time. The Facebook account which you are logged into would have to be an Admin of the Facebook page.
