Description

Is there any way to fix this? Or does youtube-dl not support Viki anymore?

[NicolasFlandrois]

I got the same error messages, same website.
Any clues or input would be a life changer.

I am seeing the same issue. Do I need to post a dump file to help troubleshoot the issue? Here is my verbose output the dump doesn't seem to give any additional or revlant infromation.
