HttpURLConnection- connect() throws Java ConnectException

Question

I use the code

public static int getResponseCode(String urlString) throws MalformedURLException, IOException {         
    URL u = new URL(urlString);  
    HttpURLConnection huc = (HttpURLConnection) u.openConnection();
    huc.setRequestMethod("GET");
    huc.connect();
    return huc.getResponseCode();  
}

to get the Response code. When I run the code, I get an exception java.net.ConnectException: Connection timed out at java.net.PlainSocketImpl.socketConnect(Native Method)

I printed the URl which makes this error and then loaded it in browser. the link was loaded, but after some time, around 2 mins. What could be the reason why the status code is not returned? And How can I handle this case?

Thanks for your help!

Try to call huc.setReadTimeout(120000); before huc.connect().

However I am afraid that something is going wrong with your server side. Why does it replies after ~2 minutes?

Yeah, at times it loads too slow. – Shari Apr 28 '15 at 14:09
I just checked the same code for google.com and stuck with the same error for URL google.co.in/intl/en/options – Shari Apr 28 '15 at 14:28
Google.com works fine for me and takes less then 1 second. It seems that something is wrong with your internet connection. – AlexR Apr 28 '15 at 15:18
yeh google.com loads but the above code throws that exception when the URL google.co.in/intl/en/options is passed to it – Shari Apr 28 '15 at 15:40
I'll disable my machine proxy and see :) – Shari Apr 28 '15 at 16:02
I got the same error...without proxy... The page loads fast but huc.connect(); has some issues – Shari Apr 28 '15 at 16:05

You are saying that it took 2 minutes to load content in the browser. Most likely, you connection times out. You can try to set a longer timeout for your connection to 3 minutes in milliseconds

huc.setConnectTimeout(1800000);

If the issue is not timeout, then most likely you have to set the proxy for your connection. Check the proxy settings in your browser and set the appropriate values. See, for example, this question, on how to do it.

I just checked the same code for http://google.com and stuck with the same error for URL http://www.google.co.in/intl/en/options/ – Shari Apr 28 '15 at 14:28
Edited my answer with another suggestion – jny Apr 28 '15 at 14:34
I have disabled the proxy but still gets this issue with some links. :( – Shari Apr 29 '15 at 04:30
That could be because of the company firewall if there is one and you go to outside links... – jny Apr 29 '15 at 13:48
