Issue with changed subtitles

[rs232]

I watched something today and realised the subs were offsync. So I logged onto my NAS where I have a subsync script based on alass that has been serving me for many years.

Logged in, synced, removed the old subs and went back to the amazon firestick player.

No matter what I do (rescan library, refresh metadata on that movie only, restart Jellyfin LXC, restart client) it still uses the old subs... like if they were cached.

Is there anything I can do to force my Jellyfin clients to fetch the new subs?

Thanks

P.S. If I force transcoding, only then it works but it seems like a waste of resources if that's not needed.

"refresh metadata" means you selected "replace all metadata" for the show/episode?

You can also try running the clean up cache scheduled tasks.

The refresh metadata :- I went to the movie, clicked on the 3 dots and selected refresh metadata

I will certainly try the clean up cache, but in general I was wondering why this is happening. In my experience re-uploading last minute subs it's a very common task and happens now and again.
I was bringing up the topic to see if things could be done differently so that we always get the latest subtitles, that's all. Perhaps disabling the caching of .srt at code level? Ultimately a small file.

I can confirm this.
Running the Clean Cache Directory task, nor Clean Transcode Directory did anything.
The OLD DELETED subtitle still gets used.

EDIT: The cache is in the browser, not sure if jellyfin can avoid this.
Deleted the browser cache and the new file gets used

If you use a reverse proxy like Nginx, you can add a "cache kill" option that tells the browser to refresh if the brower's cache is older than a specified age.

Otherwise, I don't think there is a way.  I didn't know that Jellyfin cache subs in the browser....
