Password Reset works in debug environment but does not work after deployment

I have an ASP.Net application built in Visual Studio 2015 and deployed to the Azure environment. I am trying to add the capability to allow the user to reset their password. The application sends an email to the user with a link that contains a code to validate the user. After clicking on the link, the user is sent to a page that allows them to enter a new password then click a Submit button to actually change the password. This works fine in the Visual Studio environment but fails with no indication of why after being deployed to Azure. Does anyone have an idea of what might cause this?

The original page is displayed correctly and the code is validated. The process fails when the user clicks the submit button and the standard login page is displayed.

Thanks.
