CDN Fancybox problem

Hello, I have a little problem with FancyBox for WordPress. It has worked fine for me for a long time on several version of my blog.
But recently I started using W3 Total Cache and built in CDN features (Amazon Cloudfront) on my blog, so all the images that are shown on my blog are not on the same address as the blog itself.

My blog is https://www.coma.lv
See this topic for example of Fancybox behavior – https://www.coma.lv/blog/fedde-le-grand-at-ministry-of-sound-02-04-2011/

When I’m logged into wordpress and I click on pictures, everything works as it should be. Once I’m logged out, fancybox starts to behave strange.

When I click on the image, Fancybox starts to load, I can see image is smoothly flying to the center of the screen, and at the moment when it’s supposed to stop, it just opens in empty page in top left corner

So basically what I’m asking is if there is some way to tell the plugin that he should show “external” images in a same manner he shows “local” ones.

Thank you for this great plugin!
