Failed to establish TLS version request on Android 4.4.4

Question

Here is my code for Volley:

class VolleyService {
    public RequestQueue volley(Context context) {
        if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.KITKAT) {

            try {
                ProviderInstaller.installIfNeeded(context);
            } catch (GooglePlayServicesRepairableException e) {
                Log.e("Test321", "PlayServices not installed");
            } catch (GooglePlayServicesNotAvailableException e) {
                Log.e("Test321", "Google Play Services not available.");
            }

            HttpStack stack = null;
            try {
                stack = new HurlStack(null, new TLSSocketFactory());  // WORKS FINE TILL HERE
            } catch (KeyManagementException | NoSuchAlgorithmException e) {
                e.printStackTrace();
                stack = new HurlStack();
            }
            return Volley.newRequestQueue(context, stack);
        } else {
            return Volley.newRequestQueue(context);
        }
    }

    private class TLSSocketFactory extends SSLSocketFactory {

        private SSLSocketFactory internalSSLSocketFactory;

        TLSSocketFactory() throws KeyManagementException, NoSuchAlgorithmException {
            SSLContext context = SSLContext.getInstance("TLS");
            context.init(null, null, null);
            internalSSLSocketFactory = context.getSocketFactory();
        }

        @Override
        public String[] getDefaultCipherSuites() {
            return internalSSLSocketFactory.getDefaultCipherSuites();
        }

        @Override
        public String[] getSupportedCipherSuites() {
            return internalSSLSocketFactory.getSupportedCipherSuites();
        }

        @Override
        public Socket createSocket() throws IOException {
            return enableTLSOnSocket(internalSSLSocketFactory.createSocket());
        }

        @Override
        public Socket createSocket(Socket s, String host, int port, boolean autoClose) throws IOException {
            return enableTLSOnSocket(internalSSLSocketFactory.createSocket(s, host, port, autoClose));
        }

        @Override
        public Socket createSocket(String host, int port) throws IOException, UnknownHostException {
            return enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port));
        }

        @Override
        public Socket createSocket(String host, int port, InetAddress localHost, int localPort) throws IOException, UnknownHostException {
            return enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port, localHost, localPort));
        }

        @Override
        public Socket createSocket(InetAddress host, int port) throws IOException {
            return enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port));
        }

        @Override
        public Socket createSocket(InetAddress address, int port, InetAddress localAddress, int localPort) throws IOException {
            return enableTLSOnSocket(internalSSLSocketFactory.createSocket(address, port, localAddress, localPort));
        }

        private Socket enableTLSOnSocket(Socket socket) {
            if (socket != null && (socket instanceof SSLSocket)) {
                ((SSLSocket) socket).setEnabledProtocols(new String[]{"TLSv1.1", "TLSv1.2"});
            }
            return socket;
        }
    }
}

It calls TLSSocketFactory class and then no outcome. Can anybody help me to fix this?

No reference please.

It seems you have only new TLS version support configured on your server. Some Android 4.4.4 devices do not support TLS 1.2: https://github.com/ssllabs/ssllabs-scan/issues/258

You need to enable support of older TLS versions (TLS 1.1 for example) on your webserver.
