401 Unauthorized errors on SharePoint 2013

In my SharePoint 2013 development environment I found a new issue which was not happened in past, I suddenly ran into 401 unauthorized errors.
Those errors would occur only when the pages would be rendered through the /_layouts/15/start.aspx page. This specific page is responsible for loading pages from a site using the Minimal Download Strategy feature, a new feature in SharePoint 2013 that improves client rendering performance and fluidity for navigating from one page to another page by downloading only the changes between two pages.

401 unauthorized

If you are experiencing those 401 unauthorized errors, simply disable the following feature for now.
Site Settings > Manage Site Features > Minimal Download Strategy (see the image below)

Happy SharePointing...!!!
