api is not reconnecting to websocket

[eringiso]

how to reconnect to websocket i'm not passing the websocket connection as described in the docs
passing only app_id so that api can auto reconnect but still api is disconnecting after an hour and the program exits
here is my code

const api = new DerivAPI({
    app_id
});


fx_symbols = ['frxAUDCAD', 'frxAUDJPY', 'frxAUDUSD', 'frxEURAUD', 'frxEURCAD', 'frxEURCHF', 'frxEURGBP', 'frxEURJPY', 'frxEURNZD', 'frxEURUSD','frxNZDUSD', 'frxUSDCAD', 'frxUSDCHF', 'frxUSDJPY',]

fx_candles_1m = {
    "frxAUDCAD": [],
    "frxAUDJPY": [],
    "frxAUDUSD": [],
    "frxEURAUD": [],
    "frxEURCAD": [],
    "frxEURCHF": [],
    "frxEURGBP": [],
    "frxEURJPY": [],
    "frxEURNZD": [],
    "frxEURUSD": [],
    "frxNZDUSD": [],
    "frxUSDCAD": [],
    "frxUSDCHF": [],
    "frxUSDJPY": [],
}

(async () => {
    fx_symbols.map(x => { getAllCandles(x, 60).catch(err => console.log(err)) })
})()

async function getAllCandles(symbol, tf) {
    candle_data = await api.candles({ symbol: symbol, granularity: tf, end: "latest", style: "candles", subscribe: 1 })
    candle_data.onUpdate(data => {
        if (data.raw.epoch === data.raw.open_time + tf - 1) {
            // console.log("The candle data for " + symbol + " is : ", data.raw);
            o = data.raw.open
            h = data.raw.high
            l = data.raw.low
            c = data.raw.close
            epoch = data.raw.epoch + 1
            const x = [o, h, l, c, epoch]
            const { granularity, id, open_time, pip_size, symbol, ...noA } = data.raw

            noA['epoch'] = noA['epoch'] + 1
            fx_candles_1m[symbol].push(x)
            console.log(symbol, vol_candles_1m[symbol]);

            const open = fx_candles_1m[symbol].map(d => d[0])
            const high = fx_candles_1m[symbol].map(d => d[1])
            const low = fx_candles_1m[symbol].map(d => d[2])
            const close = fx_candles_1m[symbol].map(d => d[3])

            if (fx_candles_1m[symbol].length > 14) {
              let rsi = RSI.calculate({ period: 14, values: close })
              console.log("The RSI value of " + symbol + " is ", rsi.slice(-2))
            }


            if (fx_candles_1m[symbol].length > 15) {
                fx_candles_1m[symbol].shift()
            }
            return Promise.resolve([symbol, data.raw])

        }
    })
}

what should i do to reconnect if api is disconnected

[iitsuraj]

As mentioned in the doc, it will automatically reconnect. But it is not happening. To prevent automatically close, you have to send a ping after each 30 sec.

To reconnect -

...
api.basic.onClose().subscribe(()=>api.basic.connect());
...

Now you can close this issue

Hello. I am sending {"time":1,"req_id":3,"passthrough":{}} every 30 seconds like the Binary website does, but yet my websocket client is disconnected by the server.
