Laravel 5: Migration-Route - Artisan::call('migrate', array('--force' => true)) stops

I have an migration-route in my application, the current output is:

init migrate:install...done migrate:install
init with tables migrations...

Now it stops. But the output should continue. Heres the route:

Route::get('/migrate', function () {
    try {
        try {
            echo '<br>init migrate:install...';
            Artisan::call('migrate:install');
            echo 'done migrate:install';
        } catch (Exception $e) {
            echo 'allready installed';
        }

        echo '<br>init with tables migrations...';
        Artisan::call('migrate', array('--force' => true)); // here it stops via browser
        echo 'done with migrations';

        echo '<br>clear view cache...';
        $cachedViewsDirectory = app('path.storage').'/framework/views/';

        if ($handle = opendir($cachedViewsDirectory)) {
            while (false !== ($entry = readdir($handle))) {
                if(strstr($entry, '.')) continue;

                @unlink($cachedViewsDirectory . $entry);
            }

            closedir($handle);
        }
        echo 'all view cache cleared';

        return redirect()->route('backend::dashboard');
    } catch (Exception $e) {
        Response::make($e->getMessage(), 500);
    }
});

While accessing the Shell and run the migration it will work:

-bash-4.2$ /opt/plesk/php/5.6/bin/php artisan migrate
**************************************
*     Application In Production!     *
**************************************

 Do you really wish to run this command? (yes/no) [no]:
 > yes

Why it doesn't work from route?
