对等方关闭连接（Android 5）

Question

我正在使用改造和 okHttp 与服务器进行通信。问题是 android 5 gettting 错误，它在日志中。一切都像在较低的 android 版本上的魅力一样。我尝试信任所有证书，但仍然收到此错误...知道吗？

设置改造：

RestAdapter.Builder builder = new RestAdapter.Builder()
                        .setEndpoint(config.BackendConfig.API_URL)
                        .setRequestInterceptor(requestInterceptor)
                        .setLogLevel(GeneralConfig.RETROFIT_LOG_LEVEL);
builder.setClient(new OkClient(UnsafeOkHttpClientUtil.getClient()));
RestAdapter restAdapter = builder.build();
sApiService = restAdapter.create(CervApiService.class);

设置 UnsafeOkHttpClientUtil：

 try {
    final TrustManager[] trustAllCerts = new TrustManager[]{
                        new X509TrustManager() {
               @Override
               public void checkClientTrusted(java.security.cert.X509Certificate[] chain, String authType) throws CertificateException {}

               @Override
               public void checkServerTrusted(java.security.cert.X509Certificate[] chain, String authType) throws CertificateException {}

               @Override
               public java.security.cert.X509Certificate[]getAcceptedIssuers() {
               return new java.security.cert.X509Certificate[]{};
               }
        }
};
final SSLContext sslContext = SSLContext.getInstance("TLS");
sslContext.init(null, trustAllCerts, new java.security.SecureRandom());
final SSLSocketFactory sslSocketFactory = sslContext.getSocketFactory();

OkHttpClient okHttpClient = new OkHttpClient();
okHttpClient.setSslSocketFactory(sslSocketFactory);
okHttpClient.setHostnameVerifier(new HostnameVerifier() {
          @Override
          public boolean verify(String hostname, SSLSession session) {
          return true;
      }
});
return okHttpClient;
