Unable to configure verification page

I am using username pwd as authentication method.
@adb I tried changing callback URL to http://192.168.1.10/callback but it redirects with same issue.

http://192.168.1.10/callback?error=server_error&error_description=Unable%20to%20configure%20verification%20page.&state=B0asLa4HFnr576wUz8jw.Cj9KmSPAj0x

From your previous post:

  1. Why not use app-based-URLs to get the access_token (like com.mycompany.myapp://auth0data/callback …) ?

How does this work can you explain breifly?
