javax.net.ssl.SSLHandshakeException: Remote host closed connection during handshake during web service communicaiton

I am getting javax.net.ssl.SSLHandshakeException: Remote host closed connection during handshake exception when I try to do HTTPS Post of a web service through internet. But same code works for other internet hosted web services. I tried many things, nothing is helping me. I posted my sample code here. Can anyone please help me to resolve this problem?

public static void main(String[] args) throws Exception {
	
	String xmlServerURL = "https://example.com/soap/WsRouter";
	URL urlXMLServer = new URL(xmlServerURL);
	// URLConnection supports HTTPS protocol only with JDK 1.4+ 
	Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress(
			"xxxx.example.com", 8083));
	HttpURLConnection httpsURLConnection = (HttpURLConnection) urlXMLServer
			.openConnection(proxy);
	httpsURLConnection.setRequestProperty("Content-Type","text/xml; charset=utf-8");
	//httpsURLConnection.setDoInput(true);
	httpsURLConnection.setDoOutput(true);
	httpsURLConnection.setConnectTimeout(300000);
	//httpsURLConnection.setIgnoreProxy(false);
	httpsURLConnection.setRequestMethod("POST"); 
	//httpsURLConnection.setHostnameVerifier(DO_NOT_VERIFY); 
	// send request
	PrintWriter out = new PrintWriter(
			httpsURLConnection.getOutputStream());
	StringBuffer requestXML = new StringBuffer();
	requestXML.append(getProcessWorkOrderSOAPXML());   
	// get list of user		
	out.println(requestXML.toString()); 
	out.close();
	out.flush();
	System.out.println("XML Request POSTed to " + xmlServerURL + "\n");
	System.out.println(requestXML.toString() + "\n"); 
	//Thread.sleep(60000);  
	// read response
	
	BufferedReader in = new BufferedReader(new InputStreamReader( 
			httpsURLConnection.getInputStream()));
	String line;
	String respXML = "";
	while ((line = in.readLine()) != null) {
		respXML += line;
	}
	in.close();

	// output response
	respXML = URLDecoder.decode(respXML, "UTF-8"); 
	System.out.println("\nXML Response\n");
	System.out.println(respXML);
}

Actually, there are two scenarios here. When I work as a standalone Java program I am getting the above exception. But when I try to execute in weblogic application server, I am getting the below exception: Any clue what could be the reason?

Exception: java.io.IOException: Connection closed, EOF detected

Java 7 defaults to TLS 1.0, which can cause this error when that protocol is not accepted. I ran into this problem with a Tomcat application and a server that would not accept TLS 1.0 connections any longer. I added

-Dhttps.protocols=TLSv1.1,TLSv1.2

to the Java options and that fixed it. (Tomcat was running Java 7.)

I faced the same problem and solved it by adding:

System.setProperty("https.protocols", "TLSv1,TLSv1.1,TLSv1.2");

before openConnection method.

Not an answer yet, but too much for a comment. This is clearly not a server cert problem; the symptoms of that are quite different. From your system's POV, the server appears to be closing during the handshake. There are two possibilities:

The server really is closing, which is a SSL/TLS protocol violation though a fairly minor one; there are quite a few reasons a server might fail to handshake with you but it should send a fatal alert first, which your JSSE or the weblogic equivalent should indicate. In this case there may well be some useful information in the server log, if you are able (and permitted) to communicate with knowledgeable server admin(s). Or you can try putting a network monitor on your client machine, or one close enough it sees all your traffic; personally I like www.wireshark.org. But this usually shows only that the close came immediately after the ClientHello, which doesn't narrow it down much. You don't say if you are supposed to and have configured a "client cert" (actually key&cert, in the form of a Java privateKeyEntry) for this server; if that is required by the server and not correct, some servers may perceive that as an attack and knowingly violate protocol by closing even though officially they should send an alert.

Or, some middlebox in the network, most often a firewall or purportedly-transparent proxy, is deciding it doesn't like your connection and forcing a close. The Proxy you use is an obvious suspect; when you say the "same code" works to other hosts, confirm if you mean through the same proxy (not just a proxy) and using HTTPS (not clear HTTP). If that isn't so, try testing to other hosts with HTTPS through the proxy (you needn't send a full SOAP request, just a GET / if enough). If you can, try connecting without the proxy, or possibly a different proxy, and connecting HTTP (not S) through the proxy to the host (if both support clear) and see if those work.

If you don't mind publishing the actual host (but definitely not any authentication credentials) others can try it. Or you can go to www.ssllabs.com and request they test the server (without publishing the results); this will try several common variations on SSL/TLS connection and report any errors it sees, as well as any security weaknesses.

A first step to diagnose the issue is by starting the client - and if you are running the server yourself, a private test instance of the server - by starting Java with the VM option:

-Djavax.net.debug=all

See also https://blogs.oracle.com/java-platform-group/entry/diagnosing_tls_ssl_and_https

I think you are missing your certificates.

You can try generating them by using InstallCerts app. Here you can see how to use it: https://github.com/escline/InstallCert

Once you get your certificate, you need to put it under your security directory within your jdk home, for example:

C:\Program Files\Java\jdk1.6.0_45\jre\lib\security

Let me know if it works.

I encountered a similar problem with glassfish application server and Oracle JDK/JRE but not in Open JDK/JRE.

When connecting to a SSL domain I always ran into:

javax.net.ssl.SSLHandshakeException: Remote host closed connection during handshake
...
Caused by: java.io.EOFException: SSL peer shut down incorrectly

The solution for me was to install the Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files because the server only understood certificates that are not included in Oracle JDK by default, only OpenJDK includes them. After installing everything worked like charme.

JCE 7: http://www.oracle.com/technetwork/java/javase/downloads/jce-7-download-432124.html

JCE 8: http://www.oracle.com/technetwork/java/javase/downloads/jce8-download-2133166.html

I ran into a similar issue and found I was hitting the wrong port. After fixing the port things worked great.

In my case, I got this problem because I had given the server a non-existent certificate, due to a typo in the config file. Instead of throwing an exception, the server proceeded like normal and sent an empty certificate to the client. So it might be worth checking to make sure that the server is providing the correct response.

I experienced this error while using the Jersey Client to connect to a server. The way I resolved it was by debugging the library and seeing that it actually did receive an EOF the moment it tried to read. I also tried connecting using a web browser and got the same results.

Just writing this here in case it ends up helping anyone.

Thanks to all for sharing your answers and examples. The same standalone program worked for me by small changes and adding the lines of code below.

In this case, keystore file was given by webservice provider.

// Small changes during connection initiation.. 

// Please add this static block 

      static {

        HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier()

            {	@Override

		public boolean verify(String hostname, SSLSession arg1) {

		// TODO Auto-generated method stub

            	if (hostname.equals("X.X.X.X")) {

            		System.out.println("Return TRUE"+hostname);

            		return true;

            	}

            	System.out.println("Return FALSE");

            	return false;

	          }
               });
         }


String xmlServerURL = "https://X.X.X.X:8080/services/EndpointPort";


URL urlXMLServer = new URL(null,xmlServerURL,new sun.net.www.protocol.https.Handler());


HttpsURLConnection httpsURLConnection = (HttpsURLConnection) urlXMLServer	            .openConnection();

// Below extra lines are added to the same program

//Keystore file 

 System.setProperty("javax.net.ssl.keyStore", "Drive:/FullPath/keystorefile.store");

 System.setProperty("javax.net.ssl.keyStorePassword", "Password"); // Password given by vendor
            
//TrustStore file

System.setProperty("javax.net.ssl.trustStore"Drive:/FullPath/keystorefile.store");

System.setProperty("javax.net.ssl.trustStorePassword", "Password");

I encountered this problem with Java 1.6. Running under Java 1.7 fixed my particular rendition of the problem. I think the underlying cause was that the server I was connecting to must have required stronger encryption than was available under 1.6.

I had the same error, but in my case it was caused by the DEBUG mode in Intellij IDE. The debug slowed down the library and then server ended communication at handshake phase. The standard "RUN" worked perfectly.

You May Write this below code insdie your current java programme

System.setProperty("https.protocols", "TLSv1.1");

or

System.setProperty("http.proxyHost", "proxy.com");

System.setProperty("http.proxyPort", "911");

I run my application with Java 8 and Java 8 brought security certificate onto its trust store. Then I switched to Java 7 and added the following into VM options:

-Djavax.net.ssl.trustStore=C:\<....>\java8\jre\lib\security\cacerts

Simply I pointed to the location where a certificate is.

I was using the p12 which I exported with Keychain in my MacBook, however, it didn't work on my java-apns server code. What I had to do was to create a new p12 key as stated here, using my already generated pem keys:

openssl pkcs12 -export -in your_app.pem -inkey your_key.pem -out your_app_key.p12

Then updated the path to that new p12 file and everything worked perfectly.

How you would solve it is by going to

1. Settings

2. Search"Network"

3. Choose "Use IDEA general proxy settings as default Subversion"

As per https://kb.informatica.com/solution/23/Pages/69/570664.aspx adding this property works

CryptoProtocolVersion=TLSv1.2

With base at TLSv1.2 ALERT: fatal, handshake_failure I obtained after debug with this thread previos answer

> -Djavax.net.debug=all

I went to https://www.ssllabs.com/and observed that the web server required a SSLv3 connection deprecate at june 2015, and deprecated at JDKu31 Release notes

I edited the ${java_home}/jre/lib/security/java.security at the line

jdk.tls.disabledAlgorithms=SSLv3, RC4, DES, MD5withRSA, DH keySize < 1024,
EC keySize < 224, 3DES_EDE_CBC, anon, NULL

to

jdk.tls.disabledAlgorithms= RC4, DES, MD5withRSA, DH keySize < 1024,
EC keySize < 224, 3DES_EDE_CBC, anon, NULL

As a final step I got this error

sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target [javax.net.ssl.SSLHandshakeException]

I fixed this intalling the cert with the java keytool, following this answer PKIX path building failed” and “unable to find valid certification path to requested target”

I get this error when specifying a https url and in the same url explicitly specifying an http port (instead of an https port). Removing the explicit port :8080 solved the issue for me.

Adding certificates to Java\jdk\jre\lib\security folder worked for me. If you are using Chrome click on the green bulb [https://support.google.com/chrome/answer/95617?p=ui_security_indicator&rd=1] and save the certificate in security folder.

I faced the same issue once. I think its because of the URL

String xmlServerURL = "https://example.com/soap/WsRouter";;

Check whether its a proper one or not ??

javax.net.ssl.SSLHandshakeException is because the server not able to connect to the specified URL because of following reason-

• Either the identity of the website is not verified.
• Server's certificate does not match the URL.
• Or, Server's certificate is not trusted.

This is what solve my problem.

If you are trying to use debugger make sure you breakpoint is not on URL or URLConnection just put your breakpoint on BufferReader or inside while loop.

If nothing works try using apache library http://hc.apache.org/index.html.

no SSL, no JDK update needed, no need to set properties even, just simple trick :)
