Been using nextcloud and nextcloud talk for a few years now.
Went from version 19 to eventually the current version recently, nextcloud talk was able to upload photos no issues, recently after all hte updates.
i am getting an upload error 500: internal server error. chat / texting still works but any photos / media uploaded error out.
