Веб-сокет iOS иногда не работает при сворачивании и повторном открытии ⇐ IOS

[Anonymous]

Я работаю над разработкой торговой платформы, используя SwiftUI и urlsession, URLSessionWebSocketTask, а также фоновый и передний сетевой монитор, включая Wi-Fi/мобильный Интернет. Иногда приложение не подключается после свертывания и повторного открытия, автоматического или ручного переключения сети. Он подключен к веб-сокету и запущен. и вход в веб-сокет работает, но иногда данные не принимаются с сервера без ошибок. После завершения входа в веб-сокет, как вы можете видеть в следующем журнале, данные приходят и должны быть получены. Я работаю над исправлением этой проблемы в течение последних 11 дней, но не выяснил.
