It is working for me. I think you might be running into two issues.

One, it requires a login to work. If you are just trying to access it to scrape or whatever, you need a account. I am uncertain if their API would even work with that. 

Two, another potential issue is that they use a old https cert for the hidden service. Don't know why:

It is a normal let's encrypt cert too.
