Namespace problem only works local

I'm having the following error:

Fatal error: Class 'Kse\init\Bootstrap' not found in /home/dksec173/public_html/App/Route.php on line 8

In the development the namespace are working correctly, but when uploading to the server appears this error then, I tried to change the paths to see if it worked for nothing done, my namespace is like this.

{
"require":{
    "php":">=5.6"
},

"autoload":{
    "psr-4":{
        "Kse\":"vendor/Kse/",
        "App\":"App/"
    }
}
}
