Description

For a number of shows on viki.com, the API appears to return an unexpected Unauthorized 401. If I pass my login credentials, the error changes to a 404. I've pasted the verbose logs from both types of call for the show Three Days as an example.

The v4 REST API reports this show as having 92% subtitle completion in Korean. If I add --ignore-errors, then subtitles are downloaded for the 2 first episodes, and the rest error out with 401 Unauthorized (or 404 not found, if I authorize).

The metadata for the show doesn't say that it is restricted:

This is different from, say, I am not a Robot, which the API reports to have 100% subtitle completion in Korean, but then several episodes come back with the subtitle_completions entry completely missing for Korean. In that case youtube-dl gently reports:

[zackmark29]

We are the same problem.
Earlier in the morning I can access with my credentials without 404 error.
But now it's back. I always getting 404. Maybe this is from their server side
