Я использую Jackson ObjectMapper и следующий код для чтения JSON информации из URL-адреса HTTPS:
CurrencyDto[] currencyDtos = objectMapper.readValue(new URL("https://bank.gov.ua/NBUStatService/v1/statdirectory/exchange?json"), CurrencyDto[].class);
, что вызывает следующее исключение:
2020-05-27 10:00:00.271 ERROR 30514 --- [schedulerFactoryBean_Worker-1] c.b.d.s.job.CurrencyExchangeJob : Exception occurred

Тем не менее, Я могу получить доступ к указанному URL из curl с помощью следующей команды:
curl -i -H "Accept: application/json" https://bank.gov.ua/NBUStatService/v1/statdirectory/exchange?json
В чем может быть причина этой проблемы и как ее исправить?
ОБНОВЛЕНО
Еще одно примечание: я выполняю код упоминания Java из Quartz job org.springframework.scheduling.quartz.QuartzJobBean#executeInternal method
