The UI goes not responding because the program is connecting to the network device and the UI is being run in the same Thread. You need to start a new Thread to connect network device. When UI and connection to network device are in two different threads, the UI will not freeze.

class YourThread extends Thread{  
    public void run(){  
        // Your code to connect to network device
    }

    public static void main(String args[]){  
        YourThread thread = new YourThread();   
        thread.start();  
    }  
}

Any I/O done over a slow and unstable channel such as (but not limited to) a network is bound to give not responding user interfaces. Therefore any significant I/O should be done in a separate thread.

Some of the options you have are:

Start a new thread
Create a JavaFX Task or Service, provides easiest integration in user feedback and task progress feedback
Use java 8's CompletableFuture, or a chain of these
Use reactive programming (which is CompletableFuture more or less)
