CKFinder 3 with Nginx configuration

Question

I tried to integrate CKFinder 3 with CKEditor 4.

This is my config:

CKEDITOR.replace( 'editor', {
    filebrowserBrowseUrl: 'http://localhost:8888/build/blog/admin/ckfinder/ckfinder.html'
});

Here is the result when I try to browse the files on the server: result

I see the path is correct but I can not select any files. I think I need to do something else with Nginx configurations.

Any hints for me? Many thanks!
