Brew install x fails with 401 unauthorized

[AshPowell]

I can't seem to install anything, brew doctor is clear but whenever I try to install anything it returns (for example):

* brew install [email protected]

Not quite sure what could be wrong?

Sorry my bad, I searched around but didn't see that repo issue.

Thanks!
