RSS Feed Error

Total newbie here when it comes to RSS Feeds and how they link/display. I’m guessing all of this is auto generated with WP. However, I’m starting to get 404 error notices (VIA SEO). Here is an example of a page that is trying to load and its response. Any insight is greatly appreciated. (Layman’s terms please, lol)
I’ve removed RSS feed link from displaying in the sidebar widget ‘Meta’ so I’m not even sure how peeps are getting directed to my sites RSS Feed page.
