This is an INSECURE answer. It will make the error go away, but you will be liable to MITM attacks, because you aren't verifying the certificates.


    TrustManager[] trustAllCerts = new TrustManager[]{
      new X509TrustManager() {
        @Override
        public java.security.cert.X509Certificate[] getAcceptedIssuers() {
          return new X509Certificate[0];
        }

        @Override
        public void checkClientTrusted(java.security.cert.X509Certificate[] certs,
                                       String authType) {
        }

        @Override
        public void checkServerTrusted(java.security.cert.X509Certificate[] certs,
                                       String authType) {
        }
      }
    };

    SSLContext sc = SSLContext.getInstance("SSL");
    sc.init(null, trustAllCerts, new java.security.SecureRandom());
    HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
