I set up the config correctly, and re-did it again. The app was working one week ago but now when ii press login with line button in my app it takes me to line app but with forbidden 403 screen.

What did you expect?

Get the token from the user.

What happened actually?

I got a 403 page

Your environment?

Dart SDK version: 3.1.3
flutter_line_sdk: ^2.3.6

Sample project

LineSDK.instance.setup(dotEnv.LineID).then((_) {
    print("LineSDK Prepared");
  });
  
  try {
      final result =
          await LineSDK.instance.login(scopes: ['profile', 'email', 'openid']);

      final userId = result.userProfile!.userId;
      
      return userId;
    } catch (e) {
      return Future.error('error');
    }

Hi, thanks for reporting this.

May I know does this issue only happen on iOS or Android, or does it happen on both?

Usually, if you are still under development and the app you registered in LINE Developer Console is not yet published, you will need to use the admin account of that app or use an explicitly added tester account to perform the login test. In this case, the 403 error means the account you are using is not allowed to login to this LINE channel. Can you try to check that?

Ummm, that does not sound good.

I just had a try with the flutter SDK and our example app, and seems every thing goes fine. So it might be a channel-specified setting at last.

May I know your Channel ID? I can ask for a detailed investigation to see what can be wrong.

[OussemaZaier]

yes sure

We checked the log and seems your channel works fine.

There were indeed some 403 events left (although I am not sure if these were login attempts of yours) and the reason seems to be the user is under penalty since 2023/10/31 (sorry but I cannot provide any more information about the penalty).

Can you try to change an account to perform the log in and see what can happen?

Face the same issue and I found my account also has login issue on Line App.
Am i being ban by Line? How can I find the status and any thing to provide to lift the ban?
