Как решить проблему FORWARDING_TO_NODE_FAILED в сетке селена

Question

Я работаю над сеткой селена с нескольких дней.Я создал концентратор и узел для Android на той же машине.Узел регистрируется на хабе, и исполнение также начинается.Но через некоторое время сеанс завершился неудачно и выполнение остановилось.Вряд ли будет выполнено 2-3 теста.

Пожалуйста, проверьте ниже журнал ошибок для вашей справки
