Call failed: Could not connect to Bittrex server

Http error 400 (bad request) is returned from signalr api when I try to connect

My code:

let ws = new BittrexSocketClient() 
ws.SubscribeToMarketDeltaStream(pair.symbol, fun x -> printfn "%A" x)

Could it be related to cloudflare? Downgrading to 1.2.0 which worked previously doesn’t solve the problem

No problem. I’ve pushed a fix for the connection issue, this should mean you should be able to connect again. It is however a temporary fix and I don’t know how long it will hold. Bittrex is running an older version of the socket implementation on an alternative URL(https://socket-stage.bittrex.com). This endpoint works as the old one did before the changes, but I expect the alternative endpoint to be changed or go offline somewhere in the future.

I hope this helps you while I try to figure out how to fix the problem. I created a new Issue for this: #8.

The subscribe method returns a success indicator (in C#): var ws = new BittrexSocketClient(); var result = ws.SubscribeToMarketDeltaStream(pair.symbol, data => Console.WriteLine(data)); if(result.Success) Console.WriteLine("Subscribed"); else Console.WriteLine("Oh no, something went wrong: " + result.Error.ErrorMessage);
