 Hi @gregmagn1,

 Can you provide some additional details? Which theme are you using? Also,
 have you tested this on a fresh install?

 @sabernhardt is correct in that the RSS icon is output by passing the URL
 through the `includes_url()` function. Ultimately, `is_ssl()` is called to
 detect whether the site supports SSL or not.

 It's likely code on your site is either filtering the result of
 `includes_url()` or `set_url_scheme()`, or something is incorrectly
 configured causing WordPress to guess wrong in this situation, It could
 also be an issue in Core, but there is not enough information for the
 reasons to be clear yet.
