Sorry if it is not the proper place to post this, I’ve been unable to upload images for multiple months now, all clients, plus the piefed.social site (can upload images to post but not to the body text). Most bing up similar error messages when attempting to upload:
(Wish I could upload screenshots but I cant, sorry)

Summit:
Client error. Code: 400. Message: {“code”:400,“message”:“quota_exceeded”,“status”:“Bad Request”}
.
Voyager and Photon:
Problem uploading image: quota_exceeded
Blorp, Interstellar and Thunder: only shows uploading error, Please try again.
