When downloading from my server to our iOS devices here, keeping the video quality in download settings, at original works fine. Any other video quality setting fails. Any audio setting works fine.
Playback transcoding of everything works fine on all devices local and remote.
When it fails the downloads page on the client says
Unexpected response received from server. Status code 400
Solved, just leaving this here for anyone else, I had my transcoder directory set to RAM (16GB, Synology 1019+). Logs showed running out of space. I set it back to default (blank) to use disc space, it works normally. Strange that playback transcoding worked fine with RAM, just not downloads.
When transcoding for downloads, Plex transcodes the entire file then downloads it to the client. If the temp transcode directory is too small to hold the entire file, things go south.
When transcoding for streaming, Plex keeps only a portion of the transcoded media in temp storage. Shortly after the media has streamed to the client it is discarded to make room for additional transcodes.
