There's many ways to initialize HttpClient. Some ways won't talk with the OS (fully managed) and won't be aware of the iOS proxy settings.

The best (for iOS) is generally to use the handler that uses CFNetwork, see this blog for more details. Basically it means:

var client = new HttpClient (CFNetworkHandler ());

Otherwise you'll need to set the HttpClientHandler.Proxy to CFNetwork.GetDefaultProxy. E.g.

var handler = new HttpClientHandler {
    Proxy = CFNetwork.GetDefaultProxy (),
    UseProxy = true,
};
var client = new HttpClient(handler);
