извините, я знаю, что я публиковал темы, связанные с той же темой, в течение последнего дня, но я столкнулся с другой проблемой.

Я могу нормально запустить сервер и клиент, но я могу отправить только одно слово (не могу отправить предложение по какой-то причине) от клиента, которое выводится на консоль сервера, но как только оновыводится на консоль сервера, выводит сообщение «Ошибка приема» и закрывается.
