ssl issue with RSS feed – mixed content

I recently got SSL on my site and it seems I’m having some issues now with my feed.
nothing is showing up. I’m not super techy but I’m doing my best here…

I did a scan for insecure content and got the list below. Not sure why or if it matters with my RSS feed.

I feel like there must be some button I need to click somewhere to get the feed back up and populated? It’s just empty so something isn’t connecting.

Thoughts?
Thank you!

List if it’s important:
