无法验证JWT令牌签名

Question

Solutions form other topics did not help me, so I created new ask. Each time when I want to poke(GET) my protected route with header with token I get: "Token Signature could not be verified in BaseMiddleware.php" . Also my generated tokens don't match at jwt.io I have the same 'secret' in jwt.php as JWT_SECRET in .env

I've tried to php artisan key:generate and php artisan jwt:secret

I have custom claims in User model:

public function getJWTCustomClaims()
{
return ['firstname' => $this->firstname,
'lastname' => $this->lastname,
'email' => $this->email];
}

I use Tymon\JWTAuth\Http\Middleware\Authenticate middleware to protect route. api.php: Route::middleware('jwt.auth')->get('users','UsersController@getAllUsers');

'jwt.auth' is added into Kernel.php.

I just stucked at the begining. My repo is bmbBAMBUS/vetpet at git, it's public since it's just begining.

Composer version 1.5.2 PHP 7.1.10 "tymon/jwt-auth": "1.0.0-rc.1"
