Controller for path '/apple-touch-icon-120x120-precomposed.png' not found

I am getting a sum error in my web log file.

  • Controller for path '/apple-touch-icon-120x120-precomposed.png' was not found or does not implement IController. Path :: / apple-touch-icon-120x120-precomposed.png
  • Controller for path '/apple-touch-icon-120x120.png' was not found or does not implement IController. Path :: / apple-touch-icon-120x120.png
  • Error: Controller for path '/apple-touch-icon.png' was not found or does not implement IController. Path :: / apple-touch icon.png

I have checked on all pages that I am not using thease icons in my web app.

These are files for Apple iOS devices. The user probably added your site to their home screen. IOS then tries to find those images to create a nice icon for you. You can read more about this in the Safari documentation .

Like this one, which is actually a web app but shows up as a native app:



IOS screen with web app

What you need to do is create and add these image files. This will improve your user experience.

Some IOS device is trying to get this image from your site. The ASP.MVC engine tries to get a controller named "/apple-touch-icon-120x120.png" and throws an exception. You can create a route that ignores this call and does not throw this exception:

routes.IgnoreRoute("{*apple}", new { apple = @"(.*/)?apple-touch-icon.*\.png(/.*)?" });


You should also create an image for IOS and improve the UX on IOS devices as Patrick answered.
