azure-app-service / demoapp Goto Github PK

I get this after clicking on "Sign in using Github" on the main page: http://devfinder.net/login

Here is the content of the url field:

http://www.devfinder.net/complete/github/?error=redirect_uri_mismatch&error_description=The+redirect_uri+MUST+match+the+registered+callback+URL+for+this+application.&error_uri=https%3A%2F%2Fdeveloper.github.com%2Fv3%2Foauth%2F%23redirect-uri-mismatch&state=ZtdFjT2Io0wODdXrXO4VFoyciyCoB2nu

I'm following the read.md and pressed "deploy to azure" by supplying necessary info but there's error on the "developer-finder-[name]-function" - "Microsoft.Web/serverfarms'.
Here's the error detail:
