I use VLC player for watching movies and videos. Many times I download old English movies to watch on VLC. One of the function of VLC is VLsub under the menu tab which helps me download relevant subtitles for the movie.

I recently faced an error while downloading subtitle on VLC and got the below error:

Error: code 401 'Unauthorised' (200).

Even after many attempts the same did not resolve. I even trying updating the VLC player but it did not help. I am using 3.0.11 Vetinari version on VLC.

Any help will be highly appreciated.
