java.security.cert.CertificateException: Non of the delegates checked the chain successfully Follow

День добрый!

Пытаюсь настроить нотификацию по email в связке Hub + Upsource.

1) Добавил в Hub в "доверенные сертификаты" мои корневые сертификаты.

2) Добавил в Hub в "хранилище SSL-ключей" мой личный сертификат.

3) Настроил подключение к SMTP серверу: 

    - Протокол: SMTP+TLS

    - Указал свои имя и пароль

    - Выбрал запись из "Хранилища SSL ключей"

4) При отправке тестового письма в логах Hub вижу:
