Детали проблемы

При попытке загрузить .px4log через mavftp я получаю следующую ошибку:

ubuntu<strong i="10">@ubuntu</strong>:~$ rosrun mavros mavftp download /fs/microsd/log/2016-11-01/21_43_29.px4log
Prigressbar disabled. install python-progressbar
Traceback (most recent call last):

    buf = from_fd.read(FTP_PAGE_SIZE)

    raise IOError(ret.r_errno, os.strerror(ret.r_errno))
IOError: [Errno 110] Connection timed out

Итак, я могу открыть файл, поскольку отображается главное окно roslaunch mavros:

[ INFO] [1491328759.740312395]: FTP:Open /fs/microsd/log/2016-11-01/21_43_29.px4log: success, session 0, size 263247

Но я получаю [Errno 110] Ошибка превышения времени ожидания соединения при чтении файла.
