I run this program on the Ubuntu system. Now get the following error:

python bilibili_video_download_v3-linux.py 
Imageio: 'ffmpeg.linux64' was not found on your computer; downloading it now.
Error while fetching file: <urlopen error [Errno 111] Connection refused>.

OSError: Unable to download 'ffmpeg.linux64'. Perhaps there is a no internet connection? If there is, please report this problem.

Who can tell me what happened
