This package calls Branch Native SDK functions on each platform.

The problem reported is not in the Flutter plugin, but in the Native SDK.

Please open an issue in the platform repository:

• iOS: https://github.com/BranchMetrics/ios-branch-deep-linking-attribution
• Android: https://github.com/BranchMetrics/android-branch-deep-linking-attribution

Or open a support ticket for Branch at the link

Hi @RodrigoSMarques

I've already raised a support ticket to the Branch team, but they said to open an issue here.

Hi @RodrigoSMarques

I've already raised a support ticket to the Branch team, but they said to open an issue here.

As mentioned above.

The Plugin calls the methods exposed by the Branch SDK.

The Branch SDK connects to its own services.

In the plugin code, there is no reference or connection logic to the Branch APIs, as everything is done by the SDK itself.

The error message in PlatformException was returned by the Branch SDK.

Now, looking at the error message, I notice that after the host name, 0.0.0.0 is being displayed.

Isn't this a configuration issue in your DNS?
