New Image uploads are all corrupted.

Not sure what's going on here. When I upload from my mobile app, instead of seeing images in any other client, every single one appears as a broken link. If I try to download the image, the resultant file is corrupted and won't open. Deleting them and reuploading them results in the same thing. This appears to apply to ALL my new uploads to the system.

My current server version is v1.81.1
