Mavros: Mavftp का उपयोग करके डाउनलोड/बिल्ली फ़ाइलें डाउनलोड करते समय त्रुटि: IOError [Errno 110] कनेक्शन का समय समाप्त हो गया

समस्या का विवरण

Mavftp के माध्यम से .px4log डाउनलोड करने का प्रयास करते समय, मुझे निम्न त्रुटि मिलती है:

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):
  File "/opt/ros/indigo/lib/mavros/mavftp", line 296, in <module>
    main()
  File "/opt/ros/indigo/lib/mavros/mavftp", line 292, in main
    args.func(args)
  File "/opt/ros/indigo/lib/mavros/mavftp", line 152, in do_download
    buf = from_fd.read(FTP_PAGE_SIZE)
  File "/opt/ros/indigo/lib/python2.7/dist-packages/mavros/ftp.py", line 107, in read
    _check_raise_errno(ret)
  File "/opt/ros/indigo/lib/python2.7/dist-packages/mavros/ftp.py", line 39, in _check_raise_errno
    raise IOError(ret.r_errno, os.strerror(ret.r_errno))
IOError: [Errno 110] Connection timed out

इसलिए मैं फ़ाइल खोलने में सक्षम हूं, क्योंकि मुख्य रोसलांच मावरोस विंडो प्रदर्शित होती है:

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

लेकिन मुझे फ़ाइल पढ़ने पर [Errno 110] कनेक्शन टाइम आउट त्रुटि मिलती है।
