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"
#noxp the URL of this one is https://files.schelling.pt/media_attachments/files/106/104/940/625/321/560/original/af20d51386a5e1c6.png for example and those who want to go meta
@locus It looks like this is happening again.
@WomanCorn oh no!! thanks for brining it to my attention, I'll take a look ASAP
@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!
