Имя сегмента - это случайная буквенно -цифровая строка, которая для нас ничего не значит, и каждый раз меняется, когда ошибка регистрируется. Я изменил его, чтобы соответствовать остальным из нас, и это заставило ошибку уйти. Однако другой пользователь получает ошибку даже с правильной страной.
может кто -нибудь сказать мне основную причину этой ошибки?
