C# .Net Web Api Calls Exception

Hello,

I am trying to use HttpClient and I keep getting a resource temporarily unavailable exception. It works fine as a console app but when I try using the Wearable emulator 5.5 keep getting the exception:

            var json = JsonConvert.SerializeObject(new UserCredentials
            {
                Username = user,
            });
            var data = new StringContent(json, Encoding.UTF8, "application/json");

            var url = Constants.AuthUrl + "Login";
            var client = new HttpClient();

            try
            {
                var response = client.PostAsync(url, data).Result;
                response.EnsureSuccessStatusCode();
                return true;
            }
            catch (Exception e)
            {
                return false;
            }

It keeps falling under the catch exception: “One or more errors occurred. (Resource temporarily unavailable)”

Do I need to configure something to enable api calls such as in the manifest or elsewhere or this library is not supported?

Privilages I have added:

        /internet
        /network.get
