Same here, both on Samsung smart tv and Xbox One.
.mkv with external .srt.
When I swiched from Xbox One to Samsung Tv it worked untill I paused the TV, then after resume, the subtitle stoped working. I tried to deselect and select it again but it didn’t work.
Same here for three different tizen models and plexweb. Both internal and external srt in mkv goes away.
It’s happening to me too but it’s random and not very often. Sometimes it’s enough to stop the movie and start it again but typically I cannot replicate it at will which make posting logs rather difficult. I will keep the logs option enabled on my main TV and wait for it to happen again.
For me the subtitles disappears within about a minute on ALL my movies (mkv files) longer than 90 minutes , regardless of the srt subtitles being embedded or external, while using the web player on both Microsoft Edge and Mozilla Firefox. If I play movies that are shorter (or episodes of series) the subtitles works all the way through. For me the issue seems to be associated with the length of the file, and if that’s the cause of the issue I think you’ll never going to be able to reproduce this issue with a clip of the media file.
I’m running Windows 10, Plex server Version 1.16.4.1469, Web Client Version 3.104.2, all local.
No automatic quality, no always burn subtitles, Direct Play active, Direct Stream Active.
Started the debugging, resumed a movie (No difference if I start the movie from the beginning, but then I get no subtitles at all since there rarely is any subtitles the first minute). The subtitles showed for a little longer than 30 seconds, then they disappeared. So I stopped the movie and got this log.

Same issue. Is there a fix yet?
…and today, after I installet the update (Server Version 1.16.5.1488, Web Client Version 3.108.2) VOBSUB subtitles act the same way (both internal and external) as SRT on ALL mkv files over 90 minutes.
I upgraded to Server Version 1.16.5.1488 a few days ago and since doing that subtitles randomly disappear while casting a mkv with external srt to my Chromecast. A few lines show, a couple are missing, then a few show and so on. The video’s I tested with are around 40 minutes long.
Also have the same issue. Latest PMS on syno 218+ NAS with Tizen Samsung 4.1.1. app. Every 5th line or something dissapears, i am experiencing this with dutch/english subtitles. also tries external srt, same problem. Doesnt seem a problem on my PS4 player tough, Using a local wired connection, everything is direct streaming.
+1
Another user here with the same issue. Whether streaming to my Roku/home theatre or watching right on my computer/server. Subtitles work briefly, then vanish. If you switch them off and on again, they work again briefly, and display the next line, but then they vanish once more. Makes watching anything foreign impossible. I will note they were working a few months ago, something broke after one of the updates.
Issue exists on Plex for Xbox one as well
XBOX ONE user here, same problem for the last few months. Subs not showing every 4th-5th line, makes PLEX useless for us. Streaming from a Synology 418 Play, and had no problems with subs over the years.
Same problem here!
Problem with subs.
Direct Play seems to skip some subs while playing.
Forcing media to transcode seems to work.
Running Plex for LG 4.3.0
Webos 4.1.0
Plex server 1.16.5.1554.
Works pefectly on Xplay when playing the same media.
Same problem here…after a few minutes, less then 2 minutes, the subtitles stop working.
Its very strange, this problem occurred a time ago and if i remember, it was fixed. And now the problem is back =(
Hi sa2000,
I’m also currently encountering this problem, with the latest bundled web client (v 3.108.2, server v 1.16.5.1554). I was looking at the movie since ~15 minutes without any problem, then I resumed it. That done, everytime I’m resuming it, it is working fine for ~1 minute, then subtitles are lost.
The issue still happens with or without the ‘auto adjust quality’ setting.
- does it happen with sidecar subtitles or subtitles within mkv or both
I noticed this problem several times, only with subtitles bundled in mkvs, but I’m not having a lot of sidecar subtitles, so I’m not sure it is specific to sub
- is it on local connections or remote wan connections or both
Tested only local.
- does it happen when not seeking forward / back or resuming paused playback?
I have the feeling that it happens only after resuming, but I cannot guarantee it.
- any specific Plex Web browser ?
No, just happened using Firefox and also with Chrome
- is it happening with both bundled plex web (accessible through http://127.0.0.1:32400/web or http://ip-of-server:32400/web) and hosted plex web (accessible through https://app.plex.tv/desktop ) ?
Interesting : it seems all is working fine while using the hosted plex web.
Even a 10 minutes extract is very big. In addition it is not free for sharing so I don’t think I should share it here. If you think it could help, please ask in private.

Thank you in advance for your investigation.

Thanks @maclaustre for the detailed info. It has given us some better paths to take to reproduce and debug this.

… if external subs are created and used - they work fine as far as I can tell.
…internal subs are problematic.
(pulled a bunch of subs out of stuff I’ve been watching, added them as srt files and they are very well behaved - ALL my subs are UTF-8, most packed within MKV files)
(the Roku is particularly sensitive to this ‘sub issue’. In my limited testing over the last 48 hours external subs are winning the day - internal subs have lines that go missing, then suddenly lines are duplicated. It’s a real mess)
For me, the problem is the same for subs regardless if they are part of the video file or a separate file. Seeing this problem on Samsung smart tv.
Hi All, I have updated my post “Subtitles stop working after a short time in MKV” to include download links to a test build of PMS that includes a fix for this issue.
