Server Version#: 1.21.1.3830 Player Version#: ALL [Server logs](https://support.plex.tv/articles/200250417-plex-media-server-log-files/) attached… Hi all. Server is Hetzner dedicated server, EX42-NVME, Ubuntu 18.04LTS with docker. I was sat watching Plex yesterday evening, had watched a couple of episodes without problem. Then, without warning, playback stopped mid stream and I’ve been unable to watch anything since. At first I just got the 'progress circle animation, waiting for the stream to start, but after attempts to fix the problem, I now get “Conversion failed. The transcoder exited due to an error.”. Going backwards… Plex logs state: > Error issuing curl\_easy\_perform(handle): 28 > An error occurred reading the file: /mnt/unionfs/movies/Deep Blue Sea 3 (2020)/Deep Blue Sea 3.mkv (5). > [Transcoder] /mnt/unionfs/movies/Deep Blue Sea 3 (2020)/Deep Blue Sea 3.mkv: Input/output error Docker logs state: > [cont-init.d] 40-plex-first-run: executing… > [cont-init.d] 40-plex-first-run: exited 0. > [cont-init.d] 45-plex-hw-transcode-and-connected-tuner: executing… > [cont-init.d] 45-plex-hw-transcode-and-connected-tuner: exited 0. > [cont-init.d] 50-plex-update: executing… > [cont-init.d] 50-plex-update: exited 0. > [cont-init.d] done. > [services.d] starting services > Starting Plex Media Server. > [services.d] done.

I don’t think any updates were applied and I certainly wasn’t messing with anything! Help gratefully appreciated. L (File removed) ---

An Input/output error means it encountered an error reading the file which is not a permissions error which usually indicates that the file itself is damaged. You should replace this file with a known good copy. ---

Thank you, but I think this is impossible… I’ve watched that specific file several times previously without problems. Additionally, the error occurs on every single media file in all of my libraries. The files are stored on google cloud. Perhaps it’s a connectivity / API problem? ---
