Fails to detect connection error

[SwapMarket]

This always results in "Connected to ZMQ" even when my node is not running. Ubuntu 22, elements core, zmq4 v1.2.11.

func setupSubscriber() (*zmq4.Socket, error) {
	// Set up ZMQ subscriber
	subscriber, err := zmq4.NewSocket(zmq4.SUB)
	if err != nil {
		return nil, fmt.Errorf("failed to create ZMQ subscriber: %v", err)
	}

	err = subscriber.Connect(config.Config.ZmqPubRawTx)
	if err != nil {
		return nil, fmt.Errorf("failed to connect to ZMQ: %v", err)
	}

	// Subscribe to raw transaction notifications
	err = subscriber.SetSubscribe("")
	if err != nil {
		subscriber.Close()
		return nil, fmt.Errorf("failed to subscribe to ZMQ topic: %v", err)
	}

	log.Println("Connected to ZMQ")
	return subscriber, nil
}
