Subtitles - Playback Error (new)

Server Version#: 1.42.2.10156 (Win11 NUC)
Player Version#: 10.30.6.4151 (AndroidTV)

Plex Server running on Win11 NUC, Plex client running on Shield AndroidTV, All Cat5. The majority of my content comes from the arrs.

Subtitles have worked since forever, until this week. When I attempt to select subtitles (SRT, SDH, forced…), I get a playback error immediately. Switching back to NONE fixes it. Most (but not all) titles seem affected. Edit: I notice older titles with PGS subtitle play just fine.

Not sure what might have changed at my end. I don’t think I dinked with any settings.

I’m getting the same issue since updating too, I’ve started a thread also about this..

Was working fine before updating and the crash only occurs when activating the subtitles..

Also having this exact problem. Frustrating.

I’ve been having this same issue. Workaround exists but it’s weird.

I’m running Plex on a Proxmox setup. Plex is installed through TrueNAS Scale as an app. My library is stored on a ZFS dataset. The structure is simple:

  • Plex/

    • movies

    • tv_shows

    • plex_config

All my media plays fine until I try to search for subtitles inside the Plex server. The moment I hit the subtitle search button, I get: “There was an unexpected error during playback.” Playback stops and the video won’t load again unless I back out and restart it.

The weird part is this:
When I sign into plexapp.tv in a browser and run the same subtitle search from there, it works with no issues. So it looks like my Plex server on Proxmox/TrueNAS is the one choking, not the client or my account.

Nothing unusual in my network. Proxmox host, TrueNAS VM, Plex app. Normal LAN. No VPN on the server.

I’ve already confirmed:

  • Other media on the server has the same problem.

  • Playback works fine as long as I don’t touch the subtitle search.

  • External SRT files load if they’re already in the folder.

  • The issue only appears the moment I try to pull subtitles through the built-in search.

Since plexapp.tv can search subtitles normally, it feels like either the Plex app on TrueNAS or something in the local server environment is breaking the subtitle fetch process.

If anyone has seen this recently or knows what server logs I should pull, point me in the right direction.

Yep same issue as well…
