Getting a 403 Forbidden when trying to call MyEtherAPI with Nethereum

Question

Don't know what's wrong. Here's the code:

let web3 = Web3("https://api.myetherapi.com:443")
let balanceTask = web3.Eth.GetBalance.SendRequestAsync(account.PublicAddress, 1)
balanceTask.Wait()
balanceTask.Result.ToString()

The API I'm using is https://www.myetherapi.com/ (it works with CURL!).

The exception is:

System.AggregateException: One or more errors occurred.
 ---> EdjCase.JsonRpc.Client.RpcClientUnknownException: Error occurred when trying to send rpc requests(s)
 ---> System.Net.Http.HttpRequestException:
Response status code does not indicate success: 403 (Forbidden).

Answer 1

I thought that by using web3.Eth.GetBalance API I would already be using the https://api.myetherapi.com/eth endpoint instead of the root https://api.myetherapi.com, but I was wrong, I had to use the former URL.
