iOS 17.x can no longer login and allow dropbox access on app
i, something has changed with iOS 17. My app is using the DropboxClient() api to get an auth token, which would show safari and ask for a login.
The login works, and they will get the question if they want to allow my app access. When they click on Allow, they now get the error:
Safari can't open the page because it couldn't connect to the server.
I was using the redirect uri of "http://localhost/authorize"
private const string RedirectUri = "http://localhost/authorize";
var authorizeUri = DropboxOAuth2Helper.GetAuthorizeUri(OAuthResponseType.Code, appKey, RedirectUri, state: state, tokenAccessType: TokenAccessType.Offline);
This was working fine until iOS 17 came out.
Does anyone know how to fix this? It appears that iOS 17 no longer allows safari to connect to localhost?
I am using c# (xamarin/maui) for iOS.

It looks like this is more about iOS and its interaction with local servers/Xamarin, as opposed to the Dropbox API itself. You may be better served by referring to resources about iOS or Xamarin for help with this.
For instance, I found this thread which may be helpful.
It appears HttpListener is the issue, is there another way to use Dropbox in my app? Or to at least authorize the app, because it does work fine on iOS 17 if the app has already been authorized/logged in with iOS 16
Some workaround (till real solution finding out) could be copying auth code by hands instead of using HttpListener for that. 🤷 Somehow ugly, but will work stable everywhere. 😉
Good luck.
