javax.net.ssl.SSLHandshakeException: Connection closed by peer at com.android.org.conscrypt.NativeCrypto.SSL_do_handshake(Native Method)

before api level 24 my code is working fine but it is giving me error on api level 24( 7.0 Nougat). I am not getting what's going wrong with my code.

First Approach is here :

 <?xml version="1.0" encoding="utf-8"?> <network-security-config>
   <base-config> <trust-anchors> <certificates src="system"/>
   <certificates src="user"/> </trust-anchors> </base-config>
   <domain-config> <domain includeSubdomains="true">xyz.com</domain>
   <trust-anchors> <certificates src="@raw/my_ca"/> </trust-anchors>
   </domain-config> </network-security-config>

Inside manifest file :

android:network Security Config = "@xml/network_security_config" I have included network_security_config inside res/xml/network_security_config and ca certificate is inside res/raw/my_ca.pem

Second Approach is here :

 import org.apache.http.client.HttpClient; 
 import org.apache.http.conn.ClientConnectionManager;  
 import org.apache.http.conn.scheme.Scheme; 
 import org.apache.http.conn.scheme.SchemeRegistry;

 import org.apache.http.impl.client.DefaultHttpClient;

    public class ExSSLSocketFactory extends SSLSocketFactory { 
      SSLContext sslContext = SSLContext.getInstance("TLS"); 
      public ExSSLSocketFactory(KeyStore truststore) throws 
         NoSuchAlgorithmException, KeyManagementException,KeyStoreException,
         UnrecoverableKeyException {
         super(truststore);
     TrustManager x509TrustManager = new X509TrustManager() { 
     public void checkClientTrusted(X509Certificate[] chain, String authType)  
     throws CertificateException {
     } public void checkServerTrusted(X509Certificate[] chain, String authType)    
     throws CertificateException {
      } public X509Certificate[] getAcceptedIssuers()
     { 
return null; 
} 
}; 
sslContext.init(null, new TrustManager[] {
     x509TrustManager }, null);
 } public ExSSLSocketFactory(SSLContext
     context) throws KeyManagementException, NoSuchAlgorithmException,
     KeyStoreException, UnrecoverableKeyException {
 super(null); 
sslContext = context; 
} @Override public Socket createSocket(Socket socket, String host, int port, boolean autoClose) throws IOException,
     UnknownHostException {
 return sslContext.getSocketFactory().createSocket(socket, host, port,
     autoClose); 
} @Override public Socket createSocket() throws
     IOException {
 return sslContext.getSocketFactory().createSocket(); 
}
     public static HttpClient getHttpsClient(HttpClient client) { 
try{
     X509TrustManager x509TrustManager = new X509TrustManager() 
{ 
@Override
     public void checkClientTrusted(X509Certificate[] chain, String
     authType) throws CertificateException { }
 @Override public void
     checkServerTrusted(X509Certificate[] chain, String authType) throws
     CertificateException {
 }
 @Override public X509Certificate[]
     getAcceptedIssuers() { 
return null; 
}
 }; 
SSLContext sslContext = SSLContext.getInstance("TLS"); sslContext.init(null, new
     TrustManager[]{x509TrustManager}, null); SSLSocketFactory
     sslSocketFactory = new ExSSLSocketFactory(sslContext);
     sslSocketFactory.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
     ClientConnectionManager clientConnectionManager =
     client.getConnectionManager(); SchemeRegistry schemeRegistry =
     clientConnectionManager.getSchemeRegistry();
     schemeRegistry.register(new Scheme("https", sslSocketFactory, 443));
     return new DefaultHttpClient(clientConnectionManager,
     client.getParams()); 
} catch (Exception ex) 
{ return null; 
} } }

While making http connection :

public String CallWebService(String url, String soapAction, String envelope){


final HttpClient httpClient = ExSSLSocketFactory.getHttpsClient(new DefaultHttpClient());
    HttpParams params = httpClient.getParams();
    HttpConnectionParams.setConnectionTimeout(params, 150000);
    HttpConnectionParams.setSoTimeout(params, 150000);
    HttpProtocolParams.setUseExpectContinue(httpClient.getParams(), true);
    HttpPost httppost = new HttpPost(url);
    httppost.setHeader("soapaction", soapAction);
    httppost.setHeader("Content-Type", "text/xml; charset=utf-8");

    String responseString = "";
    try
    {
        HttpEntity entity = new StringEntity(envelope);
        httppost.setEntity(entity);
        ResponseHandler<String> rh = new ResponseHandler<String>()
        {

            public String handleResponse(HttpResponse response) throws ClientProtocolException, IOException
            {

                HttpEntity entity = response.getEntity();
                StringBuffer out = new StringBuffer();
                byte[] b = EntityUtils.toByteArray(entity);
                out.append(new String(b, 0, b.length));
                return out.toString();
            }
        };

        responseString = httpClient.execute(httppost, rh);
        Log.d("Response is here....", "responseString :  " + responseString);
    }
    catch (Exception e)
    {
        e.printStackTrace();
    }

    // close the connection
    httpClient.getConnectionManager().shutdown();
    return responseString;
}

Still I am getting error:

Make sure that you have set TLS enabled from the server side.

I have faced the same issue, same javax.net.ssl.SSLHandshakeException is throwing at the time of API call.

but in my case, the following was the issue

my device was connected to the wifi but wifi router was not having the internet connection and then the exception was thrown
