Onyxia's lair

[Downfallus]

Why when trying to enter Onyxia's lair it says that this raid is closed. Has anyone else had the same problem? Attune is done, id not, tried with different raid compositions, etc.
How am I supposed to do a chain to open the Ahn'Qiraj gate without access to the raid, can someone explain? Moderator?
