Can't discover existing feed

[Stajor]

Hi.
I tried get existing feed on the page

Feedbag.find 'https://habrahabr.ru/hub/ruby/'

but got an error

Error occurred with `https://habrahabr.ru/hub/ruby/': 403 Forbidden

On the web page source I see the feed tag

  <link title="Хабрахабр / Все публикации подряд / Ruby" type="application/rss+xml" rel="alternate" href="https://habrahabr.ru/rss/hub/ruby/all/"/>

Sorry I replied only 3 years later :) This website breaks now:

Error occurred with https://habrahabr.ru/hub/ruby/': 503 Service Temporarily Unavailable`

Thoughts?
