Unauthorized error for api call laravel route JWT

I am doing login via mobile and generate token like:

{
    "token_type": "Bearer",
    "expires_in": 2255555,
    "access_token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJzdWIiOjQwLCJpc3MiOiJodHRwOi8vbXljbGllbnR3b3JrLndlYnNpdGUvdHJhbnhpdF9zY2hlZHVsZS9wdWJsaWMvYXBpL3VzZXIvbG9naW4iLCJpYXQiOjE1NzI2OTM4MzUsImV4cCI6MTU3MzA1MzgzNSwibmJmIjoxNTcyNjkzODM1LCJqdGkiOiIwdHdrZHFwNHNzcXVRM0FZIn0.Jez-RqV1AXgaApGYQNRJorsW9XiYuX63hWJddLsppVk",
    "refresh_token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJzdWIiOjQwLCJpc3MiOiJodHRwOi8vbXljbGllbnR3b3JrLndlYnNpdGUvdHJhbnhpdF9zY2hlZHVsZS9wdWJsaWMvYXBpL3VzZXIvbG9naW4iLCJpYXQiOjE1NzI2OTM4MzYsImV4cCI6MTU3MzA1MzgzNiwibmJmIjoxNTcyNjkzODM2LCJqdGkiOiJJbDk1V2g3WHRhWHM0SDMxIn0.uDoMAIj33ldKT93jnRbr8Wc3kYAdfG0AV24ka9R5k68"
}

but it does not being authorized for further processing of application and give me

Unauthorized error. for other api requests.

I am using route middleware `auth:api'

and inside kernal.php, I have

controller:

        $credentials = $request->only('email', 'password');

         try {

                return response()->json(['error' => 'The email address or password you entered is incorrect.'], 401);
            }

$refresh_token=$this->refresh_token($request);

        }
else{

    $token=$request->refresh_token;

}

return response()->json(["token_type" => "Bearer",'expires_in' => 2255555,'access_token' => $token, 'refresh_token'=>$refresh_token]);


   }
