title: Java CertificateException "No subject alternative names matching IP address ... found"
body: <p>I'm trying to implement a selfsigned certificate into my webserver, and it's working already with firefox and chrome (both from the server itself and from a remote machine)... but I can't get it to work with java. I've already created a keystore file that contains my certificate, but every time I try to connect to the Server it gives me a SSLHandshakeException: <code>javax.net.ssl.SSLHandshakeException: java.security.cert.CertificateException: No subject alternative names matching IP address 192.168.178.71 found</code></p>
  
  <p>The code I'm using for this test is: </p>
  
  <pre><code>public static void main(String[] args) {
           System.setProperty("javax.net.ssl.keyStore",                    HTTPStest.class.getResource("keystore.jks").getFile());
              System.setProperty("javax.net.ssl.keyStorePassword",           "lead"); 
          URL url;
              InputStream is = null;
              BufferedReader br;
              String line;
  
              try {
                  url = new URL("https://192.168.178.71/");
                  is = url.openStream();  // throws an IOException
                  br = new BufferedReader(new InputStreamReader(is));
  
                  while ((line = br.readLine()) != null) {
                      System.out.println(line);
                  }
              } catch (MalformedURLException mue) {
                   mue.printStackTrace();
              } catch (IOException ioe) {
                   ioe.printStackTrace();
              } finally {
                  try {
                      if (is != null) is.close();
                  } catch (IOException ioe) {
                      // nothing to see here
                  }
              }
  
      }
