ERROR: Signature extraction failed on youtube videos

Currently, I am getting the 'ERROR: Signature extraction failed' on some youtube videos.
While I am trying to execute the below:
youtube-dl https://www.youtube.com/watch?v=HXbq49vLRC8 -F
It sadly gives me some error as:

[youtube] HXbq49vLRC8: Downloading webpage
[youtube] HXbq49vLRC8: Downloading video info webpage
