Binance Futures Testnet Websocket

Hello, I want to use a websocket for BinanceFutures Testnet. However, I could not establish a connection. The code block is as follows. Where am I making a mistake?

The value of startResult returns false.

var client = new BinanceClient(new Binance.Net.Objects.Spot.BinanceClientOptions
{
     FuturesUsdtBaseAddress = "wss://stream.binancefuture.com/",
     ApiCredentials = new ApiCredentials(_options.ApiKey, _options.ApiSecret)
});

var startResult = client.FuturesUsdt.UserStream.StartUserStream();
if (!startResult.Success) throw new Exception($"Failed to start user stream: {startResult.Error}");

Oh I see what is wrong. You’re passing the websocket address to the Rest api client. The BinanceClient class is used to communicate with the Rest api, the BinanceSocketClient class is used to connect to streams.

When using the BinanceClient to start the user stream (which is the correct thing to do before actually subscribing with the socket client) you should set the base address property in the options to the Rest address of the testnet, not the websocket address.
