Description

Tried downloading an episode of Hunting Hitler on History Vault but it doesn't even detect the website anymore.

@remitamine May I ask why this is considered a duplicate? The only other issue existing for this site is #18460 and that was asking for the site to be implemented. That was almost two years ago.

I have good faith that this is not a duplicate issue.

It's a duplicate of #23363
