HTTP404: NOT FOUND while loading dxicons.woff file

Hi,
not sure where we can configure the path to load below files from subfolder .I am facing issue while loading below files from subfolder however its working perfectly while using the root directory.

HTTP404: NOT FOUND - The server has not found anything matching the requested URI (Uniform Resource Identifier).
GET - http://detdev.duke-energy.com/dxicons.woff2

I check few article regarding to setup MIME type which is already configured in my config file.

when I deploy code in IIS in root directory, its working perfectly but as soon as I move to subfolder , it does not work.

much appreciate for any suggestions.
