java - SSLHandShakeException No Appropriate Protocol

Question

I recently added SSL to my website and it can be accessed over https. Now when my java application tries to make requests to my website and read from it with a buffered reader it produces this stack trace

Im not using a self signed certificate the cert is from Namecheap who uses COMODO SSL as the CA to sign my certificate. im using java 8

javax.net.ssl.SSLHandshakeException: No appropriate protocol (protocol is disabled or cipher suites are inappropriate)
at sun.security.ssl.Handshaker.activate(Handshaker.java:503)

at sun.security.ssl.SSLSocketImpl.startHandshake(SSLSocketImpl.java:1387)
at sun.net.www.protocol.https.HttpsClient.afterConnect(HttpsClient.java:559)

My code is very basic and simply tries to read the page on my site using a buffered reader

 private void populateDataList() {
    try {
        URL url = new URL("https://myURL.com/Data/Data.txt");
        URLConnection con = url.openConnection();
        con.setRequestProperty("Connection", "close");
        con.setDoInput(true);
        con.setUseCaches(false);

        BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));
        String line;
        int i = 0;
        while((line = in.readLine()) != null) {
            this.url.add(i, line);
            i++;
        }
    }   catch (Exception e) {
        e.printStackTrace();
    }

}

Ive tried adding my SSL certificate to the JVM's Keystore and Ive also even tried to accept every certificate (which defeats the purpose of SSL I know) with this code

 private void trustCertificate() {
    TrustManager[] trustAllCerts = new TrustManager[] {
            new X509TrustManager() {
                public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                    return new X509Certificate[0];
                }
                public void checkClientTrusted(
                        java.security.cert.X509Certificate[] certs, String authType) {
                }
                public void checkServerTrusted(
                        java.security.cert.X509Certificate[] certs, String authType) {
                }
            }
    };
    try {
        SSLContext sc = SSLContext.getInstance("TLS");
        sc.init(null, trustAllCerts, new java.security.SecureRandom());
        HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
    } catch (GeneralSecurityException e) {
    }
    try {
        URL url = new URL("https://myURL.com/index.php");
        URLConnection con = url.openConnection();
        BufferedReader br = new BufferedReader(new InputStreamReader(con.getInputStream()));
        String line;
        while((line = br.readLine()) != null) {
            System.out.println(line);
        }

    } catch (Exception e) {

    }
}

Im stumped and any help would be much appreciated!

Answer 1

In $JRE/lib/security/java.security:

jdk.tls.disabledAlgorithms=SSLv3, TLSv1, RC4, DES, MD5withRSA, DH keySize < 1024, 
EC keySize < 224, 3DES_EDE_CBC, anon, NULL

This line is enabled, after I commented out this line, everything is working fine. Apparently after/in jre1.8.0_181 this line is enabled.

My Java version is "1.8.0_201.
