Hi, I can connect to BitMEX using production API credentials, but I cannot connect to https://testnet.bitmex.com. Connection using testnet API credentials fails. StockSharp.Bitmex.dll version 4.4.15.0. I suspect that I’ve to change the endpoint somehow? I didn’t find any documentation in https://github.com/StockSharp/StockSharp/tree/master/Samples/Bitmex/SampleBitmex and https://doc.stocksharp.com/html/81f33924-b166-42c1-8ced-f7e9468f86b5.htm The connection log is attached. Thanks
