Images not loading on Caldera Forms page

Hey everyone,
I recently started having a problem on one of the pages for my website. Images load on all pages except for one. I have a static page and these are the same images on every other page (header, footer, widgets) but they started not to load a few days on my join page. I have tried purging the cache ect, turning off image optimization and nothing seems to work. The only difference on this page vs the rest of the website is that its the Caldera Forms page.

The page I need help with: [log in to see the link]
