I recently found that I was getting this same message "Playback failed because the media is not supported by this client" on almost all video files, running Jellyfin server on my Windows 10 desktop, and playing from client Android phones and tablets, in Chrome browser. Most of my video files were .avi xvid encoded movies, although .mp4 files seemed to work fine. This didn't seem to happen to me the first few months since I started using Jellyfin last December. I never found a resolution for this in Chrome, even though I tried to disable the "allow playing files that require transcoding" settings in the User settings. The workaround I found is to install the Jellyfin Android app instead of using the web browser interface. All issues went away immediately using the app. I am still curious what happened though.
