Laravel 5, some routes 404 not found

Part of my Nginx file

    server {
listen 80;
#listen 443 ssl;
server_name bla.com;
root "/bla/bla";

#disable_symlinks off;

index index.html index.htm index.php;

charset utf-8;

location / {
    #rewrite ^([^.]*[^/])$ $1/ permanent;
    try_files $uri $uri/ /index.php;
}

location = /favicon.ico { access_log off; log_not_found off; }
location = /robots.txt  { access_log off; log_not_found off; }

access_log off;

sendfile off;

client_max_body_size 100m;

location ~ \.php$ {
    try_files $uri =404;
    fastcgi_split_path_info ^(.+\.php)(/.+)$;
    fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    include fastcgi_params;
    #fastcgi_intercept_errors off;
    #fastcgi_buffer_size 16k;
    #fastcgi_buffers 4 16k;
    #fastcgi_connect_timeout 300;
    #fastcgi_send_timeout 300;
    #fastcgi_read_timeout 300;
}

location ~ /\.ht {
    deny all;
}

For example, this route:

     Route::group(['prefix' => '/api/v1'/*, 'middleware' => 'auth'*/],              

         function () {
             Route::get('/music/groups', 'Music\GroupsController@index');
         }
     });

Gives me 404

But if I add this route .. it works (hence the extra C):

   Route::get('/musicc/groups', 'Music\GroupsController@index');

Can it have anyhting to do with the same name ? Music and music. The controller is in App\Http\Controllers\Music\GroupsController

Namespace is App\Http\Controllers\Music;
