Android io.reactivex.exceptions.UndeliverableException:io.grpc.StatusRuntimeException:CANCELLED:调用被中断

在做出如下例外情况后，grpc呼叫被取消：

rpc调用是：

  @Override
public Observable<ConfigurationResponse>    uploadConfiguration(ConfigurationRequest request, String action) {

    return Observable.create(e -> {
        try {

            ConfigurationRequest configurationRequest =
                    ConfigurationRequest.newBuilder(request)
                            .setMeta(getMeta(action))
                            .build();

            CONFIGURATION_LOGGER.info("Configuration Request: " + " Server IP: " + Configuration.SERVER_IP);
            CONFIGURATION_LOGGER.info("Configuration Request: " + " Request: " + configurationRequest);

            checkInternetAvailability();

            ConfigurationResponse configurationResponse = machineOperationsServiceStub.getConfiguration(configurationRequest);

            CONFIGURATION_LOGGER.info("Configuration Response " + "Response: " + configurationResponse);

            e.onNext(configurationResponse);

        } catch (Exception ex) {
            CONFIGURATION_LOGGER.info("Getting Configuration " + " Exception: " + ex);
            e.onError(ex);
        }
    });
}

它在不同的线程池中给出了这个错误&它使应用程序崩溃。它的发生如此频繁
