I have images back! The problem was that the security certificate expired 12 days ago (cc @locus fyi), I enabled them by opening up an image directly in my browser and clicking "view anyway"
@TetraspaceGrouping hey thanks for this, it helped me figure out what was wrong; i knew the primary certificate wasn't expired, but the `files.` subdomain was using an older, incorrect one, and needed to be renewed independently. should be working now!
@WomanCorn oh no!! thanks for brining it to my attention, I'll take a look ASAP
@locus It looks like this is happening again.
