React native websocket error on Android

I'm using simple Websocket connection on react native framework, with ios it works great, but on Android I'm in 70% getting message: WebSocketEvent {type: "error", message: null} and this error is closing socket connection. I don't know why does it happenning?

My code is:

self._ws = new WebSocket("wss://fe01-ws.wearetv.com/platform/simchacr/some_code");

    var initPing = function (){
        pingInterval = setInterval(function(){
            ping.timestamp = new Date().getTime();
            ping.sequenceNumber++;
            ping.params.timestamp = ping.timestamp;
            ping.params.sent_ts = ping.timestamp;
            ping.params.seq = ping.sequenceNumber.toString();
            self._ws.send(JSON.stringify(ping.params));
            console.log("Ping is sent");
            isPinged = false;
            pongTimeout = setTimeout(function(){
                if (isPinged === false) {
                    self._ws.close();
                }
            }, PONG_DELAY);
        }, PING_INTERVAL);
    };


    var initConnection = (function me() {
        isPinged = false;

        self._ws.onopen = function () {
            console.log("Connection opened");
            initPing();
        };
        self._ws.onerror = function(error) {
            console.error(error);
            self._ws.close();
        };
        self._ws.onclose = function() {
            console.log("Connection closed");
            clearInterval(pingInterval);
            clearTimeout(pongTimeout);
            clearTimeout(reconnectTimeout);
            reconnectTimeout = setTimeout(function(){
                console.log("Ping reconnection");
                initConnection();
                initPing();
            }, PING_RECONNECT_TIME);
            isPinged = false;
        };
        self._ws.onmessage = function (message) {
            //var data = JSON.parse(message.data);
            //console.log(data);
            //if (data[REQUEST_PROPERTY_MAIN] === "ACK") {
            //    clearTimeout(pongTimeout);
            //    clearTimeout(reconnectTimeout);
            //    isPinged = true;
            //}
            //self._getMessage(data);
        };
        return me;
    })();
