С 20.04.2018 сервера Меркурия поменяли сертификат безопасности. Теперь они используют сертификат, выданный центром сертификации, который не считается доверенным при подключении к Меркурию из старых платформ (⇐8.2).
При этом 1С выдаёт ошибку: Ошибка работы с Интернет: Удаленный узел не прошел проверку
Для исправления этого неудобства необходимо добавить содержимое файла
