Not able to establish a connection over Socket.io in swift

I'm using socket.io framework for swift. I am trying to connect via websockets API, I have a method, which is getting called in the viewDidLoad of the ViewController. I have declared my manager and the socketClient globally, i'll put the code for the method below:

private func setupSockets() {
    manager = SocketManager(socketURL: URL(string: "http://kaboom.rksv.net")!, config: [.log(true), .compress])
    socket = SocketIOClient(manager: manager, nsp: "/watch")//manager.defaultSocket
    socket.onAny {print("Got event: \($0.event), with items: \($0.items)")}

        socket.on("data", callback: { (data, ack) in
        print(data)
    })

    socket.on("error", callback: { (data, ack) in
        print(data)
        print(ack)

    })


    socket.on("connect", callback: { (data, ack) in
        print(data)
        print(ack)


        self.socket.emit("ping", [])

    })

    socket.connect()
}

The issue I face is that the connect callback is not getting called and hence, I'm not able to emit a ping message. Here are the logs:

Use namespace like below:

let socket = socketManager.socket(forNamespace: "/watch")

Declaration should look like this , you forget to set the port

   let manager = SocketManager(socketURL: URL(string: "http://localhost:8080")!, config: [.log(true), .compress])
   let socket = manager.defaultSocket
