Signalr - endless $.connection.hub.disconnected event?

I'm using Signalr 2.2.1 with a successful websocket connection.

Here are the events for different states : ( simplified for brevity)

var hub = $.connection.moveShapeHub;


$.connection.hub.start().done(function ()
{
    console.log("hub started successfully");

}).fail(function () { console.log('Could not Connect!'); });


$.connection.hub.disconnected(function ()
{
    $.connection.hub.start();
    console.log('Connection disconnected')
});

My app is working fine as expected.

But look what happen when I disable the network card ( I access my computer not via localhost but via dynamic dns which goes to the world and then comes back to my computer)

At first you can see websocket connection error (I see it multiple times)

WebSocket connection to 'ws://xxxxxx.ddns.net/signalr/reconnect?transport=webSockets&messageId=d-C68A95E5-g%2C1&clientProtocol=1.5&connectionToken=%2FDJL8eAtVtSA3XKeap4Js3IrbkCm56C%2FWKCQtApGiMroWAgnzNoRHmJ0Y2LpIdWWWL%2BfY3dXvJqYHFfby1XYii0ibPpKM55PQuZyf9aH4k9JHIT79lWoMWBasIpa9Gjk&connectionData=%5B%5D&tid=2' failed: Error in connection establishment: net::ERR_INTERNET_DISCONNECTED

And then you see endless calls(!!!) to the negotiate

Wait ~15 seconds to see the endless loop :

Question

How can I fix those endless calls ? Or alternatvly - increase delay in those "negotiate calls" -say every 2 seconds ( instead of blazing fast endlessly 0.1 seconds)

Edit

I've changed this code :

$.connection.hub.disconnected(function ()
    {
        $.connection.hub.start();
        console.log('Connection disconnected')
    });

to this (remove hub start):

$.connection.hub.disconnected(function ()
    {
             console.log('Connection disconnected')
    });

And now I see only this message :

But now I'm losing all the basic idea of "trying restart connecting" in case of disconnect. So I ask again is there any reasonable solution or at least trying "restart the connection every 2 seconds" ?
