org.openqa.selenium.WebDriverException: java. net .ConnectException: не удалось подключиться к локальному хосту

Question

Я использую Chrome Version 80.0.3987.87 (Official Build) (64-bit), и у меня начались проблемы с запуском тестов. Вот журнал из сборки Gradle в IntelliJ (я обрезал повторяющиеся сообщения):

Я попытался обновить Selenide до последней версии (5.6.1) - не помогло, такая же проблема возникает. Самое непонятное, что это происходит не каждый раз - иногда это работает через весь набор тестов, иногда перерывы после одного теста, а иногда в середине.

Как я могу диагностировать, что может быть не так?
