here is the code

  @Test
  public void testOpenPosition() throws Exception {
    if (API_KEY != null && SECRET_KEY != null && PASSPHRASE != null) {
      ExchangeSpecification spec =
          ExchangeFactory.INSTANCE
              .createExchange(OkexExchange.class)
              .getDefaultExchangeSpecification();
      spec.setApiKey(API_KEY);
      spec.setSecretKey(SECRET_KEY);
      spec.setExchangeSpecificParametersItem(OkexExchange.PARAM_PASSPHRASE, PASSPHRASE);

      final Exchange exchange = ExchangeFactory.INSTANCE.createExchange(spec);

      exchange.getTradeService().getOpenPositions().getOpenPositions().forEach(System.out::println);
    }
  }

Hi, @a1265137718
Most likely this is an error at the operating system level and not Java.
It is also possible that you have a proxy somewhere in Java.
