java - SSLHandshakeException : SSL handshake aborted: ssl=0xbe6af938: I/O error during system call, 连接由对等方重置

Question

出现以下错误:javax.net.ssl.SSLHandshakeException: SSL handshake aborted: ssl=0xbe6af938: I/O error during system call, Connection reset by peer 改造类:

public class RetrofitClientInstance {

    private static Retrofit retrofit;
    

    public static Retrofit getRetrofitInstance() {
        
        if (retrofit == null) {
            Gson gson = new GsonBuilder().setLenient().create();

            retrofit = new retrofit2.Retrofit.Builder()
                    .client(HelperOkHttpClient.getOkHttpClient())
                    .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
                    .baseUrl(BASE_URL)
                    .addConverterFactory(GsonConverterFactory.create(gson))
                    .build();
        }
        return retrofit;
    }
}

此方法中出现错误/异常:

private void makeRequestToSecondAuthStep(ArrayList<String> creds) {

        AuthCheckHTTP defectSpecific = RetrofitClientInstance.getRetrofitInstance().create(AuthCheckHTTP.class);
        Observable<ResponseSingleRequestAuth<Object>> observableDefectsRelated = defectSpecific.getAuthCheck();
        observableDefectsRelated
                .subscribeOn(Schedulers.io())
                .observeOn(AndroidSchedulers.mainThread())
                .doOnNext(specficDefects -> {
                    Log.w("ASYNCLI", "In defectspecif");
                    if (HelperIsNull.isNull(creds.get(3))) {
                        creds.set(3, creds.get(5));
                    }
                    DataBaseHelper.deleteAllData();
                    PublisherNotificationSync.getInstance().setLastSyncDate(INITIAL_DATE);
                    writeCredentialsToLocalDb();

                    actMain.runOnUiThread(new Runnable() {
                                              @Override
                                              public void run() {
                                                  presenterAuthAct.downloadData();
                                              }
                                          }
                    );
                })
                .doOnError(
                        throwable -> {
                            HelperToastMaker.createMessage(App.getAppContext(), "У вашего пользователя нет прав на пользования мобильным приложением");
                            ((Button) mainAct.findViewById(R.id.button)).setEnabled(true);
                            AppProperties.setpIdentificator("");
                        }
                ).doOnComplete(() -> {
            Log.w("Event", "Fired i guess");
        }).subscribe(new Observer<ResponseSingleRequestAuth<Object>>() {
            @Override
            public void onSubscribe(Disposable d) {

            }

            @Override
            public void onNext(ResponseSingleRequestAuth<Object> objectResponseSingleRequestAuth) {

            }

            @Override
            public void onError(Throwable e) {
              // do nothing
            }

            @Override
            public void onComplete() {

            }
        });

    }
}

也许您可以通过某种方式将标准 (SSL) 添加到此 Retrofit 类中，以前有没有人遇到过这个或类似的问题？
可能是什么问题呢？几个月前 - 一切正常，项目没有被触及(存档)
先感谢您
UPD:与证书无关，这是 SAP，他们自己更新

我不确定这里是否有足够的信息让我准确诊断您的问题，但错误表明 SSL 握手错误，这通常对我来说表明问题不在代码中，而是在证书/可接受的加密算法中为沟通 channel 。
Retrofit 是一个 REST 框架，所以我假设您在其上编写了一个 API，然后 Retrofit 处理您的 HTTP session 和 SSL 内容。你说解决方案突然停止工作。您的改造依赖是最新的吗？也许让您的依赖项保持最新，重新打包您的应用程序并查看是否有效？
