Existing RSS feed URLs are reporting as 404 errors

The 404 error log is showing many feed URLs that are already present. For example, if you open the following links in browser, all are displaying the feed page. But they are also showing in the 404 error log section:

Example 1: https://www.rswebsols.com/web-design-that-can-increase-its-usability/feed/

Example 2: https://www.rswebsols.com/benefits-of-using-css-for-web-pages/feed/

Example 3: https://www.rswebsols.com/digital-camera-repair-service-of-teleplan/feed/
