Laravel user registration 5.4?

Question

I am trying to register a user in the table and is returning the following error:

SQLSTATE[HY000] [1045] Access denied for user 'homestead'@'localhost' (using password: YES) (SQL: select count(*) as aggregate fromuserswhereemail= ****@gmail.com)

My connection code:

'mysql' => [
            'driver' => 'mysql',
            'host' => env('DB_HOST', 'localhost'),
            'port' => env('DB_PORT', '3306'),
            'database' => env('DB_DATABASE', 'teste'),
            'username' => env('DB_USERNAME', 'root'),
            'password' => env('DB_PASSWORD', ''),
            'unix_socket' => env('DB_SOCKET', '/tmp/mysql.sock'),
            'charset' => 'utf8',
            'collation' => 'utf8_unicode_ci',
            'prefix' => '',
            'strict' => false,
            'engine' => null,
        ],

My Controller:

protected function validator(array $data)
    {
        return Validator::make($data, [         
            'name' => 'required|max:255',
            'user' => 'required|max:100',
            'email' => 'required|email|max:255|unique:users',
            'password' => 'required|min:6|confirmed',
        ]);
    }


    protected function create(array $data)
    {
        return User::create([
            'name' => $data['name'],
            'user' => $data['user'],
            'email' => $data['email'],
            'password' => bcrypt($data['password']),
        ]);
    }

My Model:

protected $fillable = [
        'name', 'user', 'email', 'password',
    ];
