I have followed the getting started tutorial which seems to work however the loginTask is never flagged as completed. In playfab I can see that the user does actually log in. Debugging through I can see that PlayfabSysHttps.cs never returns from here: httpResponse = await _client.PostAsync(fullUrl, postBody); httpResponseString = await httpResponse.Content.ReadAsStringAsync(); After the PostAsync it just hangs and never returns.
