Ionic Web Application - Back Navigation makes page blank (White Screen)

I have created the ionic web application for mobile browser using

ionic platform add browser
ionic build browser

then copy the www folder and hosted it into the PHP server.

Everything works fine but i have only one issue when the back pressed from the browser page goes blank (White screen). When i did ionic serve that time back navigation has no issue. This problem only happen when i host it into Server. Is there any solution to avoid the blank screen ?

ionic version 4
