[SOLVED] Flutter macOS: AppwriteException: null, Connection failed (0)

I try to connect with Cloud beta current version via macOS Flutter app (iOS is working)
I get following error: AppwriteException: null, Connection failed (0) after _account.createEmailSession
I added the macOS platform in the dashboard under the project
Any ideas whats causing this error?

appwrite: ^9.0.0
flutter: 3.7.12

The same code works perfectly fine for iOS?

https://appwrite.io/docs/getting-started-for-flutter#macOS

Have you followed this for macOS?

Yes
I added the platform
Maybe the package name must be different to the iOS app?

Can you share the code in which you're connecting the client to Appwrite cloud

In short:

final client = Client(endPoint: "https://cloud.appwrite.io/v1");
_account = Account(client)

final session = await _account.createEmailSession(
      email: username,
      password: password,
    );

I have only one instance of client for all requests

in the cloud already updated to version 1.3.x for client version 9.0.0?

No, 8.1.0

can this cause the issua although ios is working?

I don't think so but it's worst a shot

have you granted internet permissions?

where do I need to do this?

Maybe this will help: https://stackoverflow.com/questions/61196860/how-to-enable-flutter-internet-permission-for-macos-desktop-app
