Category RSS for MailChimp

I am trying (in vain) to get the category specific RSS Feed URLs for my site. I have read through all the forums and none have helped. At this point, I think I just need someone to say “this is your answer”.

My intention is to use these feed URLs for MailChimp so people can receive RSS campaigns for specific categories or all of them. Not sure if MailChimp is why the regular feed URL isn’t working (I had downloaded Category – RSS Widget Menu and it just gives me this: https://104homestead.com/category/around-the-home which MailChimp says isn’t valid)
