It's not really a matter of permission, since an RSS feed's purpose requires it to be publicly accessible. In this case it just looks like they don't have an RSS feed anymore that you could connect to. You'll have to ask them if they intend to make it accessible again at some point. If not, you'll have to update your "feed" manually or do without it.
