Futures Testnet - Kline not working

[timclaeren]

Two days can't receive any Kline information using futures testnet, code is below, everything working on mainnet, and two days ago everything was fine on testnet, now receiving nothing

func (){
        wsKlineHandler := func(event *futures.WsKlineEvent) {
            fmt.Println(event)
        }
        errHandler := func(err error) {
            fmt.Println(err)
        }
        _, _, err := futures.WsKlineServe("BTCUSDT", "1m", wsKlineHandler, errHandler)
        if err != nil {
            fmt.Println(err)
        }
    }()
