@ilwoody I used to get 502 frequently for video uploads. The web client won't display it, but the server sends a more verbose error message that can be seen in the browser's developer tools.
@ilwoody I had no problem with that whenever I've done it. But then, I shouldn't be smug. I got a new router that'll let me connect to all the Internet EXCEPT my ISP's site.
@flutergork@ilwoody@Gargron I used to get errors when uploading unedited pictures from Google Photos, because they were above the server's limit (which is 1 or 2MB, iirc).
Simply doing auto color correction would re-encode the pic at a slightly lower JPEG quality, making it work.
