In case it helps my fellow #mastoadmin crowd... infosec.exchange had a pervasive problem where thumbnails/previews for images and links would not show, either for things posted locally or for posts from other instances in the home or federated timelines.

It was only when I made that setting change AND I shut down sidekiq on the second server that this started working correctly. I still do not know why the second sidekiq server caused that, but here we are.
