Yt-dl has insecure cert?

The hyperlinks on their site gives me a big warning message about their cert:

> This server could not prove that it is yt-dl.org; its security certificate is from *.aries.uberspace.de. This may be caused by a misconfiguration or an attacker intercepting your connection.

Does anyone else get this? I don't remember seeing that last time I tried to download it:
