Laravel delay running auth middleware to after my own middleware has run

In laravel 5.5, I have created a middleware that sets the database connection for a tenant. I use that middleware in a route group like so.

Route::group(['domain' => '{site}.kyinfosysteem.loc', 'middleware' => 'association'], function() {
    Route::get('/', function ($site) {
        return view('welcome');
    });

    Auth::routes();

    Route::get('/home', 'HomeController@index')->name('home');
});

What happens now, is that the /home route runs the default auth middleware before my association one. This causes auth to fail, because it is trying to use the master database, which does not have a users table. How could i set the auth middleware to run after mine? Tried removing auth from the construct of HomeControllerand doing this:

Route::group(['domain' => '{site}.kyinfosysteem.loc', 'middleware' => 'association'], function() {
    Route::get('/', function ($site) {
        return view('welcome');
    });

    Auth::routes();

    Route::group(['middleware' => 'auth'], function() {
        Route::get('/home', 'HomeController@index')->name('home');
    });
});

but that does nothing...
