Laravel 5.5 — Laravel-Snappy PDF Generation — & gt; RuntimeException из-за UnknownNetworkError

Я использую 5.5 фреймворка и недавно загрузил 0.12.5 (dev-master) пакета wkhtmltopdf-amd64, чтобы попытаться устранить эту ошибку.

Я знаю, что это обычно происходит из-за URL-адресов SSL (https) в html, НО я получил файл, который пытаюсь распечатать, и он работает в моей производственной среде.

Я изменил новый код в тестовой среде (которая была изменена для использования шрифта awesome 5) назад, чтобы он использовал только v4 этого. Насколько я могу судить, ссылки в файлах (где 1 работает, а 1 нет) совпадают.

Существуют ли другие проблемы в HTML-файле моего тестового файла, которые могут вызвать ошибку, показанную здесь:

HTML, созданный на тестовом сервере

HTML, созданный на рабочем сервере (это НЕ выдает ошибку)
Иными словами, внешний вид, который требует 6 ссылок https для форматирования, успешно создает PDF с использованием двоичного файла 0.12.4.

И двоичные файлы 0.12.4 и 0.12.5 (при попытке в тестовой среде) не смогли создать PDF-файл, что привело к приведенному выше тексту ошибки.
