Update 1: This is an issue with cloudflare, we are having issues with the account that hosts the site, we are contacting cloudflare support about the issue.
Update 2: we have switched s3 providers and images should be working again, older images may be missing, we will have to do a merge with the old s3 storage backup into the new provider, we plan to do this soon, but all new images will work as expected, sorry for the issues and thanks for your patience and kindness while we were working on the fix
Update 3: we have created a new ticket with cloudflare support with more information so that hopefully they take this issue more seriously.
For those experiencing issues uploading pictures, that is a separate issue we were not aware of until yesterday, that should be fixed now
EDIT: Federation issues:
It seems like federation is working now and the issues with photo uploading and admin settings getting 500 errors was also causing federation issues. Some posts were, to my understanding, in a federation window that has passed so the data is no longer there to be federated to our instance but future posts should federate properly. Please let me know if you see any other more recent posts that aren’t federating properly.
It's the underlying cause of the issue. (Well, that and dealing with cloudflare.)
Yes (that's what cloudflare appears to be for). Which is causing your stupid proxy to produce this shit instead of an image:
You'll notice how the first link, which is what your site produces, craps out (because your cloudflare account isn't working properly, as tends to happen with cloudflare, no surprise there), while the second link, which is the original URL reconstructed from your mangling, works perfectly. (I grabbed it from some random post in the front page, the content is irrelevant but harmless).
So keep the fucking original URL instead of hijacking it with some stupid unnecessary proxy and it'll fucking work!
Q.E. fucking D., for fuck's sake! 🤷♂️
