To make the problem clear I will give this code example :
from pytube import YouTube
video = YouTube("https://www.youtube.com/watch?v=sMvk9kE94uE")
streams = video.streams.filter(progressive=True)
# let's say the video with 720p quality is the third one in the list
print(streams[2].url)
This exact code, when I run it on my windows 10 computer, it returns the right URL that can be downloaded, and when I run it on my ubuntu Linux server it returns a URL that doesn't work and just keeps loading.
Here is a photo :
Sometimes, and only sometimes, the left code returns a correct URL.
I don't understand why is that. The only difference is the operating system.
Please try to provide me with any suggestion to solve this problem. If any more detail is needed, I will add it directly.
