javax.net.ssl.SSLException: Write error: ssl=0x7f70604080: I/O error during system call, Broken pipe

Benutze ich die Nachrüstung für das hochladen von Bild-zu-server, aber habe ein seltsames Problem

api-Methode Erklärung:

@POST("/uploadImage")
@Multipart
Result<UploadImageResponse> uploadImage(@Part("image") TypedByteArray image);

rest adapter user custom client:

OkClient client = new OkClient(getUnsafeOkHttpClient());

wo

private OkHttpClient getUnsafeOkHttpClient() {

    try {
        //Create a trust manager that does not validate certificate chains
        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 null;
            }
        }};

        //Install the all-trusting trust manager
        final SSLContext sslContext = SSLContext.getInstance("SSL");
        sslContext.init(null, trustAllCerts,
                new java.security.SecureRandom());
        //Create an ssl socket factory with our all-trusting manager
        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;
    } catch (Exception e) {
        throw new RuntimeException(e);
    }
}
