Images not loading on mastodon.social issue has been partially fixed. My flexify.io credit has run out while I was outside so they shut off the virtual bucket I had in place while fixing file permissions on Exoscale. I've now redirected the traffic directly to Exoscale. Caveat: Not all file permissions have been fixed yet so some images will still not load. But newly uploaded ones from the last few days will be fine.
@Gargron Thanks Eugen. For remaining on tip of things.
