Solution:
Actually while developing a SharePoint hosted add-in you should give a developer site. You should create a developer site using the developer site template and you should give that url in your visual studio reference.

You can follow How to create developer site in Office 365 SharePoint 2013 Online? and also you can check SharePoint 2013 Developer Site Template overview.

The above solution works for me.

Also you can check the below solution which I followed from this msdn article.
