Получение ошибки при запуске Jenkins с сертификатом PEM

Question

Я недавно настроил свой ci-сервер jenkins и хотел добавить сертификацию HTTPS SSL. Я получил сертификат от Let's Encrypt, и у меня есть сертификат и закрытый ключ в виде файлов PEM. Согласно документации, я могу передать пути двух файлов в jenkins с помощью аргументов командной строки (я использую интегрированный сервер Winston в jenking Файл WAR). Моя команда запуска выглядит так:

java -jar jenkins.war 
     --httpPort=8080
     --httpsPort=443
     --httpsCertificate=path/to/certificate.pem
     --httpsPrivateKey=path/to/key.pem

Но когда я запускаю jenkins, я получаю эту ошибку:
