Exception in thread "main" java.net.UnknownHostException: en.wikipedia.org - Jsoup

Question

I am getting error while running below code. I tried more than 10 urls but the error is same (java.net.UnknownHostException).

public class ExtractPage {
    public static void main (String args[]) throws IOException{
        String url = "https://en.wikipedia.org/wiki/English_language";
        Document doc = Jsoup.connect(url).get();
    }
}

Below is Error StackTrace:

I found similar problem statements over internet but dint found the exact solution to run my code, Anyone can help ? Thanks in advance.

Can you access the url in other ways from the machine this is running on? For example with `curl`? — Federico klez Culloca, Jan 23 '20 at 13:05
I can access the url from my browser. Infact when I tried "https://www.google.com", I am getting the same exception. — Keshav Singh, Jan 23 '20 at 13:08
Is this running inside some sort of container? Are you behind a proxy? — Federico klez Culloca, Jan 23 '20 at 13:10
I am running the code from my office PC. so not sure about proxy/containers. — Keshav Singh, Jan 23 '20 at 13:13
If the browser works a proxy may be configured in the browser's options. Check there. — Federico klez Culloca, Jan 23 '20 at 13:14
It worked in my personal laptop. I think my organisation uses proxy that's why I was not able to connect from there. BTW thanks @FedericoklezCulloca — Keshav Singh, Jan 24 '20 at 07:07
If you discover the address of the proxy you can then see [this thread](https://stackoverflow.com/questions/7482748/how-to-add-proxy-support-to-jsoup) for how to use it with jsoup. — Federico klez Culloca, Jan 24 '20 at 07:48

@Keshav Singh, your code is correct. There seems to be a network issue at your end.

Please find the successfully executed code.

import java.io.IOException;

import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;

public class ExtractPage {

    public static void main(String[] args) {

          String url = "https://en.wikipedia.org/wiki/English_language";
            try {
                Document doc = Jsoup.connect(url).get();
                System.out.println(doc);
            } catch (IOException e) {
                e.printStackTrace();
            }
    }

}

Do we know what could be causing the network issue? – dagra May 27 '21 at 00:12

You may have to set proxy along with the Jsoup as shown below

Document doc = Jsoup.connect(<website.com>)
                    .proxy(<host>, <port>)
                    .get();
