SSL-соединение не может быть установлено, см. внутреннее исключение

У меня есть проект интеграции, где мой RestAPI вызывает службы WCF другого проекта для выполнения некоторых операций CRUD.

Мой проект построен на .net core 2.2.102. Я развернул свой проект в среде БЕТА (в моем случае PROD) и указал URL-адреса PROD служб WCF. Затем я получаю эту ошибку при попытке выполнить запрос из моего приложения: не удалось установить SSL-соединение, см. внутреннее исключение.

Я попытался воспроизвести его на моем локальном. но он отлично работает с моей локальной машины, когда я указываю на БЕТА-URL-адреса служб WCF. Я проверил настройки брандмауэра. Я вижу, что они в порядке.

Что может быть возможной основной причиной этого? У меня нет доступа к БЕТА-версии, поэтому я не могу развернуть ее методом проб и ошибок. Я прикрепляю трассировку стека внутренних исключений.
