Optimized images no longer loading after Discourse upgrade

We have a thread that had images

But after upgrading discourse, the optimized images are no longer loading:

https://community.intercoin.org/uploads/default/optimized/1X/f22bf9d2060da5c430d51fd0b9165980683f07be_2_690x366.gif

They appear as broken images when loaded in a mobile phone.
What can we do to fix this? Regenerate optimized images somehow, and update the src of images?
I guess we can edit the comments and copy and re-paste all the images.

Anyone?

I can’t seem to understand why it happens only on mobile.
