У меня есть скрипт, работающий на грани в IoT Azure, который выполняет некоторые вычисления, и как только программа вычисляет нужные цифры, я отправляю их в два места:
- Назад в IoT Hub
- Размещено на локальном URL с запросом lib
Теперь вот где возникает проблема;после нескольких дней запуска и исправления программа остановилась, и журналы показывают следующую проблему:

Следовательно, проблема связана с запросом, но я не знаю, было ли ограничение числа повторных попыток,
Есть идеи, как удалить или увеличить это число?
