Issue in page when open in new tab (component)

I'm using Angular 8 : A simple project for login,forgot password and some other basic components.

 When I tried to open privacy policy page on new tab its showing a blank page(using prod build) but it working on my local system.

same things happen when I type the page name / component name in url for ex.  login(Localhost:4200/Login) and other pages it shows blank page (without any error)

Can any one help in this.
