Subtitle Search returns 'unable to load subtitles' error

Plex Media Server

Server Version#: 1.19.5.3112
Player Version#: 4.34.3

Lately I’ve been having trouble looking up subtitles via the ‘Subtitles’ > ’ Search…’ feature.
Whenever I look for a subtitle it returns a ‘unable to load subtitles’ error.

The first few weeks, this feature seemed to work fine, but lately, it has just stopped returning results altogether.

Looking through the log files while downloading, I found this error in Plex Media Server.log but I’m a little stuck on how to debug further.

Any help would be greatly appreciated :slight_smile:

Welp, guess I’ll have to write my own implementation to download subtitles automatically using OpenSubtitlesDownloader… :expressionless:

its broken for me too. lastest update broke it

I ended up writing a wrapper around OpenSubtitlesDownloader that I can schedule to run every night in order to pick up new movies/shows’ subtitles…

It’s far from perfect (in my limited testing OSD has a failure rate of about 20% in finding the right subtitle). But it’s better than nothing and hopefully Plex will remedy this issue somewhere in the future.

I can share my code if there’s interest.

To follow-up… by enabling the automatic subtitle download feature, I was able to get subtitles working for any new additions to my plex library:

So I’m now just using my script to add subtitles for the content that was already there prior to enabling the download feature.
