Problem namespace only works local

Question

I’m having the following mistake:

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 properly, however when going up to the server appears this error there, I tried to change the paths to see if it works but nothing done, my namespace is like this..

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

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