Images not loading

My website https://healthymomsmagazine.net is an online magazine and is hosted by GoDaddy. All of our images are hosted on MaxCDN. Recently they started not showing up. Some posts show blank space where the image is supposed to be, the featured images in our slider are missing, and some of the thumbnails just show a square box without an image.

The site also takes over 30 seconds to load with Chrome because it is waiting for the CDN. I contacted support at MaxCDN and they think it is a hosting/ server issue. I trimmed down my plugins, optimized the images and did all that I could to try to fix this. I don’t have time to wait on hold with GoDaddy support regarding this. It has been like this for a few weeks now and I need a solution ASAP.

Is there a code I can insert in one of my files to fix this? I don’t want to download any more plugins. If I can get rid of more plugins and replace them with a code that would be fantastic . I just need my site to load fast and all the images to appear properly.

Please help!
